% \section{The {\sc docstrip} modules}
%
% \subsection{Code common to all modules}%
% The following may look a bit klootchy, but we
% want to require only one place in this file
% where the version number is stated,
% and we also want to ensure that the version
% number is embedded into every generated file.
%
% Here is some code for the document style,
% which can be run under both \LaTeX2.09 or
% \LaTeXe.
% If the latter, we terminate reading of the
% style file and
% simply load the document class instead.
% If the former, we provide dummy
% definitions for the \LaTeXe\ commands
% appearing in the style file.
%
% \begin{macrocode}
%<style>\ifx\ProvidesFile\undefined
%<style> \def\next{}%
%<style>\else
%<style> \def\next{%
%<style> \endinput
%<style> \@obsoletefile{aastex.cls}{aastex.sty}\LoadClass{aastex}%
%<style> }%
%<style>\fi\next
%<style>\def\ProvidesFile#1[#2]{\message{File: #1 #2}}%
% \end{macrocode}
%
% To start with, we declare that
% this file can only be used with \LaTeXe.
% An appropriate message is displayed if
% a different \TeX{} format is used.
% \begin{macrocode}
%<*doc|class|guide|sample|table>
\NeedsTeXFormat{LaTeX2e}[1995/12/01]%
%</doc|class|guide|sample|table>
% \end{macrocode}
% As desired, the following modules all
% take common version information:
% \begin{macrocode}
%<class>\ProvidesClass{aastex}%
%<style>\ProvidesFile{aastex.sty}%
%<guide>\ProvidesFile{aasguide.tex}%
%<symbols>\ProvidesFile{aassymbols.tex}%
%<sample>\ProvidesFile{sample.tex}%
%<table>\ProvidesFile{table1.tex}%
%<*doc>
\expandafter\ProvidesFile\expandafter{\jobname.dtx}%
%</doc>
% \end{macrocode}
%
% \subsection{Version and Date}%
%
% The following line contains, for once and for all,
% the version and date information.
% By various means, this information is reproduced
% consistently in all generated files and in the
% typeset documentation.
% \begin{macrocode}
[2005/06/22 5.2/AAS markup document class]%
% \end{macrocode}
%
% \subsection{The driver module \texttt{doc}}
%
% Because the only uncommented-out lines of code at the beginning of
% this file constitute the \file{doc} module itself,
% we can simply typeset the |.dtx| file directly,
% and there is thus rarely any need to
% generate the ``doc'' {\sc docstrip} module.
% Module delimiters are nonetheless required so that
% this code does not find its way into the other modules.
%
% The |\end{document}| command concludes the typesetting run.
%
% \begin{macrocode}
%<*doc>
% \end{macrocode}
%
% \subsection{The ltxdoc configuration file}
%
% This {\sc docstrip} module generates a local file \file{ltxdoc.cfg},
% which contains customizing commands for
% when the programmer documentation \file{aasclass.dtx} is typeset.
%
% In particular, we request the production of an index of macros.
%
% For more information on such proccessing options,
% see the standard \LaTeX\ file \file{ltxdoc.dtx}.
%
% \begin{macrocode}
\begin{filecontents}{ltxdoc.cfg}
% ltxdoc.cfg - local copy for aasclass directory
\AtBeginDocument{\CodelineIndex\EnableCrossrefs}
\AtEndDocument{\PrintIndex}
\end{filecontents}
% \end{macrocode}

\maketitle
\aastex\ provides a markup system and formatter for authoring
papers to be submitted electronically to a number of
astonomy journals.
This file embodies the document class,
the implementation, and the user documentation.
The distribution point for \aastex\ is
\file{ftp://ftp.aas.org/pubs/aastex50.zip}, which contains
fully unpacked, prebuilt runtime files and documentation.
To use this document class, you must have a working
\TeX\ installation equipped with \LaTeXe.
Certain features of \aastex\ (such as landscape tables)
require a PostScript printer.
To install, retrieve the distribution,
unpack it into a directory on the target computer,
and move the file \file{aastex.cls}
into a location in your filesystem where it will be found by \LaTeX.
If you will be using the |astro| font in your \aastex\ documents,
put the file \file{Astrosym.tfm} where \TeX\ can find it
(Textures users will put \file{Astrosym metrics} into their \file{TeX fonts} folder).
Now either install the (ATM-compatible) PostScript Type~1 fonts
appropriate to your operating system and \TeX\ implementation,
or install the MetaFont source (both provided with \aastex).
In any case, you are responsible for properly installing the
|astro| font on your system.
Then print out the user guide \file{aasguide.dvi} and
the two sample documents, \file{sample.dvi} and \file{table.dvi}.
If need be, print the programmer's manual \file{aasclass.dvi}.
\StopEventually{}\tableofcontents
\section{Processing Instructions}
The document class \file{aastex.cls} (plus other macro files),
the user documentation \file{aasguide.tex},
and the sample documents
are generated from this file, \file{aasclass.dtx},
via the {\sc docstrip} facility of \LaTeX.
The documentation that you are now reading is generated from
the same file by simply typesetting it with \LaTeX.
\subsection{Build Instructions for V5.0}
You may bootstrap \aastex\ solely from \file{aasclass.dtx}.
Prepare by installing \LaTeXe\ on your computer,
then carry out the following steps:
\begin{enumerate}
\item
Within an otherwise empty directory,
typeset \file{aasclass.dtx} with \LaTeX;
you will obtain the typeset documentation you are now reading,
along with the installer \file{aasclass.ins} and the file \file{Read.Me}.
Note that you will have to run MakeIndex (using the \LaTeX\ standard
\file{gind.ist}) and retypeset with \LaTeX\ as appropriate.
\item
Now typeset \file{aasclass.ins}, thereby generating
macro files \file{aastex.cls}, and \file{aastex.sty}, user documentation \file{aasguide.tex}, \file{aassymbols.tex},
the sample file \file{sample.tex} and the sample table
\file{table.tex}.
\item
Install \file{aastex.cls} and \file{aastex.sty}:
move them to a location
in your file system where they will be found by \LaTeX.
\item
Typeset \file{aasguide.tex} to obtain the user documentation
(you will have to run MakeIndex and retypeset as needed),
\item
Typeset the sample file \file{sample.tex}.
\end{enumerate}
For your reference,
there are six \TeX\ log files appended to this file
(locate them by searching on |preloaded format=|).
They result respectively from typesetting
\file{aasclass.dtx}, \file{aasclass.ins}, \file{aasguide.tex},
\file{aassymbols.tex},
\file{sample.tex}, \file{table.tex}.
\subsection{Build Instructions for V4.1}
When you bootstrap V5.0, you automatically create the files rquired for the
V4.1 distribution, which consists of a number of the documents for V4.0
along with style files to patch it, plus revised sample documents.
The user guide for V5.0 is also the guide for 4.1; relevant differences
appear in an appendix.
The files for version~4.1 are located in a separate part of the distribution tree,
a directory called \file{./V4.1/}.
To build, simply copy the file
\file{aastex.sty} into the 4.1 directory.
Then copy
the sample files \file{sample.tex}, \file{sample2.tex}, and \file{samptbls.tex},
and the sample tables
\file{table1.tex}, \file{table2.tex}, \file{table3.tex}, and \file{complext.tex}
into the same directory.
Finally, copy
\file{aasguide.dvi} and \file{aasguide.ps} into the same directory.

by A. Ogawa (ogawa@teleport.com)%
}%
% \end{macrocode}
%
% \subsection{Type Size}
% \begin{macro}{\aas@ptsize}
% The macro |\aas@ptsize| works very much like
% the |\@ptsize| macro of \file{classes.dtx},
% but in this class.
% \begin{macrocode}
\newif\iflong@abstract
\global\long@abstractfalse
\DeclareOption{10pt}{\newcommand\aas@ptsize{0}}%
\DeclareOption{11pt}{\newcommand\aas@ptsize{1}}%
\DeclareOption{12pt}{\newcommand\aas@ptsize{2}}%
% \end{macrocode}
% \end{macro}
%
% \subsection{Landscape Orientation}
% The option \Lopt{landscape} is disabled in this document class.
% \begin{macrocode}
\DeclareOption{landscape}{\OptionNotUsed}%
% \end{macrocode}
%
% \subsection{Equations Numbered by Section}
%
% The option \Lopt{eqsecnum} invokes |\eqsecnum|, q.v.
% \begin{macrocode}
\DeclareOption{eqsecnum}{\AtEndOfClass{\eqsecnum}}
% \end{macrocode}
%
% \subsection{Longabstract}
% The option \Lopt{longabstract} cause the long abstract text to break into
% next page within preprint2. Using this option has no effect with other styles.
%
% \begin{macrocode}
\DeclareOption{longabstract}{\global\long@abstracttrue}
% use when abstract exceed title page
% \end{macrocode}
%
% \subsection{Set Text Justified Rather Than Ragged Right}
%
% The option \Lopt{flushrt} causes the text to set
% justified, hyphenated rather than ragged right, nohyphens
% as is normal in the |manuscript| substyle.
%
% Asserting this option presently has no effect in
% the other substyles because they make no changes
% to the justification. If this situation changes,
% be careful to supply the appropriate hook as needed.
%
% \begin{macrocode}
\DeclareOption{flushrt}{\let\opt@just\just@just}%
\let\opt@just\@empty
\def\just@just{%
\@rightskip\z@skip
\rightskip\@rightskip
\pretolerance=100\relax
}%
% \end{macrocode}
%
% \subsection{Use Tight Leading Rather Than Doublespace}
%
% The option \Lopt{tighten} causes the text to set
% with tight leading rather than double spacing
% as is normal in the |manuscript| substyle.
%
% Asserting this option presently has no effect in
% the other substyles because they make no changes
% to the justification. If this situation changes,
% be careful to supply the appropriate hook as needed.
%
% Not! In the manuscript substyle, leading is doubled and
% the |\tightenlines| command is effectively disabled.
% So, what gives?
%
% \begin{macrocode}
\DeclareOption{tighten}{\def\opt@tighten{\tightenlines}}%
\let\opt@tighten\@empty
% \end{macrocode}
% \subsection{Summary}%
% The following are local options to this document class.
%
% \begin{center}
% \begin{tabular}{ll}
% |eqsecnum|&equations numbered by section\\
% |flushrt|&set text justified\\
% |tighten|&use tight leading\\
% \end{tabular}
% \end{center}
%
% \subsection{Substyle Options}%
% An \aastex\ document must have exactly one class option selected from
% the following list; the default is |manuscript|.
% This option determines the substyle, signifying the
% basic formatting choice for the document.
% \begin{center}
% \begin{tabular}{ll}
% \bfseries Class Option&\bfseries Purpose\\
% |manuscript|&Manuscript (the default)\\
% |preprint|&Preprint\\
% |preprint2|&Preprint in two columns
% \end{tabular}
% \end{center}
% Note that in the case of |preprint2|, we immediately signal
% the base document class that the two-column grid will be used.
% \begin{macrocode}
\DeclareOption{manuscript}{\def\aas@substyle{manuscript}\long@abstractfalse}
\DeclareOption{preprint}{\def\aas@substyle{preprint}\long@abstractfalse}
\DeclareOption{preprint2}{\def\aas@substyle{preprint2}\@twocolumntrue}
% \end{macrocode}
%
% For backward compatibility, we declare options corresponding to V4.0
% \begin{macrocode}
\DeclareOption{aasms4}{\substitute@option{aasms4}{manuscript}}%
\DeclareOption{aaspp4}{\substitute@option{aaspp4}{preprint}}%
\DeclareOption{aas2pp4}{\substitute@option{aas2pp4}{preprint2}}%
\DeclareOption{aj_pt4}{\substitute@option{aj_pt4}{preprint}}%
\DeclareOption{apjpt4}{\substitute@option{apjpt4}{preprint}}%

\def\aas@substyle{manuscript}%
\AtEndOfPackage{%

}%
% \end{macrocode}

%
% \subsection{Font Complement}
% \begin{macro}{astro}
% Invoking the |astro| class option causes the
% astro font to be loaded at the appropriate size.
% \begin{macrocode}
\DeclareOption{astro}{\AtBeginDocument{\load@astro}}%
% \end{macrocode}
% \end{macro}
%
% \subsection{Default Option}%
% \begin{macrocode}
\DeclareOption*{\PassOptionsToClass{\CurrentOption}{article}}%
% \end{macrocode}
%
% \subsection{Executing Options}
%
% Here we execute the default options to initialize certain
% variables.
% \begin{macrocode}
\ExecuteOptions{letterpaper,oneside,onecolumn,final}%
% \end{macrocode}
%
% The |\ProcessOptions| command causes the execution of the code
% for every option \Lopt{FOO}
% which is declared and for which the user typed
% the \Lopt{FOO} option in his
% |\documentclass| command. For every option \Lopt{BAR} he typed,
% which is not declared, the option is assumed to be a global option.
% All options will be passed as document options to any
% |\usepackage| command in the document preamble.
%
% Note that |\ProcessOptions| is followed by |\relax| in order to
% signal conclusively that the *-form has not been used.
% \begin{macrocode}
\ProcessOptions\relax
% \end{macrocode}
%
% \begin{macro}{aas@size@manuscript}
% \begin{macro}{aas@size@preprint}
% \begin{macro}{aas@size@preprint2}
% Now that local options have been processed, we know what substyle to use.
% We execute a procedure to pass the proper type size option to
% the base class.
% Note that the macro |\aas@ptsize| acquires a value as a side effect of this
% processing.
%
% As should be evident, the manuscript substyle mandates 12point, the default
% size for preprint is 11 point, and that for two-column preprint is 10 point.
%
% Implementation note: here we must use \LaTeXe's cumbersome methods because we
% have not yet defined the Boolean control macros.
% \begin{macrocode}
\@namedef{aas@size@manuscript}{%
\def\aas@ptsize{2}%
\pass@aassize
}%
\@namedef{aas@size@preprint}{%

}%
% \end{macrocode}
% \end{macro}
% \end{macro}
% \end{macro}
%
% \begin{macro}{\pass@aassize}
% The procedure |\pass@aassize| is the bottleproc for passing the size option
% down to the base class, which is taken to be the |article| class.
% \begin{macrocode}
\def\pass@aassize{%
\expandafter\PassOptionsToClass\expandafter{\expandafter1\aas@ptsize pt}{article}%

% \section{Loading the Base Document Class and Packages}
%\aastex\ is a variant of the standard \LaTeX\ article class:
% |CTAN://macros/latex/unpacked|.
% \begin{macrocode}
\LoadClass{article}[1995/12/01]%
% \end{macrocode}
%
% We always load the standard \LaTeX\ symbol package:
% |CTAN://macros/latex/base|.
% \begin{macrocode}
\RequirePackage{latexsym}%
% \end{macrocode}
%
% We always load the standard \LaTeX\ extended graphics package:
% |CTAN://macros/latex/packages/graphics|.
% \begin{macrocode}
\RequirePackage{graphicx}%
% \end{macrocode}
%
% The AMS |amssym| package provides access to symbols in the AMS fonts:
% |CTAN://macros/latex/packages/amslatex|.
% \begin{macrocode}
\RequirePackage{amssymb}%
% \end{macrocode}
%
% The contributed \LaTeX\ |natbib| package:
% |CTAN://macros/latex/contrib/supported/natbib|.
% \begin{macrocode}
\RequirePackage{natbib}%
\newcommand{\bibstyle@aas}{\bibpunct{(}{)}{;}{a}{}{,}}
\@citestyle{aas}
% \end{macrocode}
%
% The standard \LaTeX\ verbatim package may not be really necessary, but
% this code may serve as a model for loading other classes:
% |CTAN://macros/latex/packages/tools|.
% \begin{macrocode}
\RequirePackage{verbatim}%
% \end{macrocode}
%
% Here ends the code for the document class.
% The next section provides code that is common to
% the document class and document style.

% \subsection{A Special Note on the Two-Column Preprint Style}%
%
% It is not the objective of the \aastex\ project to develop \LaTeX\
% styles that produce pages that mimic the appearance of specific AAS
% journals.
% However, it would be nice to offer format options within the preprint
% styles so that output format can be changed.
% (Within the ``manuscript''
% style, |\tighten| is available, and this effectively turns off the
% doublespacing.) The primary motivation behind this idea is to provide
% some definitions that permit institutions to distribute ``pretty''
% preprints with this package.
% (Of course, I make the glaring assumption that I
% can determine what someone else will think is pretty.)
%
% This style has the principle function of setting up two-column output.
% Although it should be painfully obvious, it is important to remember
% that text lines are considerably shorter when two of them are typeset
% side by side on a page. Long equations, wide tables and figures, and
% the like, may not slide into this format without some adjustments.
% It is our opinion that great effort to adapt copy and markup for
% two-column pages is counterproductive; remember that the main goals
% of this package are to enable comprehensive tagging of the article
% and, secondarily, to produce ``correct'' draft (or referee) format
% pages.
%
% I elect not to impose a format for the front matter, although I feel
% it looks best if the title, author, abstract, and keyword material is
% typeset on its own page at full text width. The author may supply the
% |\twocolumn| command wherever desired, and, for that matter, is free
% to switch between |\onecolumn| and |\twocolumn| modes.
% (However, this is bad form.)
% \begin{verbatim}
% \twocolumn % Enter two-column page grid
% \onecolumn % Enter one-column page grid
% \end{verbatim}
% Note that the two-column page grid begins at the point |\twocolumn|
% appears in the text, and if that point is before the frontmatter,
% the latter will get typeset in two-column mode
% along with the rest of it.
% For purposes of producing ``pretty'' output,
% it is probably desirable to
% put this command after the abstract and keywords, just before the body
% of the paper.
% If the command is not specified explicitly,
% the document class will automatically switch between the one-column
% and two-column page grid as needed.
%

% |\revtex@org| is the sponsoring organization;
% and
% |\revtex@genre| gives the applicable journal, if specified.

% Set the text width
% \begin{macrocode}

% \end{macrocode}
% \end{macro}
%
% \begin{macro}{\textheight}
% The |\textheight| is the height of text
% (including footnotes and figures, excluding running head and
% foot).
%
% \begin{macrocode}

% \end{macrocode}
% \end{macro}
%
% \subsubsection{Vertical spacing}
%
% \begin{macro}{\headheight}
% \begin{macro}{\headsep}
% \begin{macro}{\topskip}
% The |\headheight| is the height of the box that will contain the
% running head. The |\headsep| is the distance between the bottom
% of the running head and the top of the text. The |\topskip| is
% the |\baselineskip| for the first line on a page; \LaTeX's output
% routine will not work properly if it has the value 0pt, so do not
% do that!
% \begin{macrocode}
\setlength\headheight{.15in}%

% \subsubsection{Margins}
%
% \begin{macro}{\marginparsep}
% \begin{macro}{\marginparpush}
% The horizontal space between the main text and marginal notes is
% determined by |\marginparsep|, the minimum vertical separation
% between two marginal notes is controlled by |\marginparpush|.
% \begin{macrocode}
\setlength\marginparsep {10\p@}%
\setlength\marginparpush{5\p@}%
% \end{macrocode}
% \end{macro}
% \end{macro}
%
% Now we can give the values for the other margin parameters. For
% native \LaTeXe, these are calculated.
% \begin{macro}{\oddsidemargin}
% \begin{macro}{\evensidemargin}
% \begin{macro}{\marginparwidth}
%
% Values for two-sided printing:
% \begin{macrocode}
\setlength\oddsidemargin {0in}%
\setlength\evensidemargin {0in}%
\setlength\marginparwidth {0in}%
% \end{macrocode}
% \end{macro}
% \end{macro}
% \end{macro}
%
% \begin{macro}{\topmargin}
% The |\topmargin| is the distance between the top of `the
% printable area'---which is 1 inch below the top of the
% paper--and the top of the box which contains the running head.
%
% \begin{macrocode}
\setlength\topmargin{0in}%
% \end{macrocode}
% \end{macro}
%
% \subsection{Paragraphing}
%
% \begin{macro}{\lineskip}
% \begin{macro}{\normallineskip}
% These parameters control \TeX's behavior when two lines tend to
% come too close together.
% \begin{macrocode}
\setlength\lineskip{1\p@}%
\setlength\normallineskip{1\p@}%
% \end{macrocode}
% \end{macro}
% \end{macro}
%
% \begin{macro}{\@doubleleading}
% \begin{macro}{\@tightleading}
% The two alternatives for leading are defined here.
% \begin{macrocode}
\def\@doubleleading{1.6}%
\def\@tightleading{1.1}%
% \end{macrocode}
% \end{macro}
% \end{macro}
%
% \begin{macro}{\baselinestretch}
% This is used as a multiplier for |\baselineskip|.
% Note that if this command
% doesn't resolve to ``empty'' any \texttt{plus} or \texttt{minus}
% part in the specification of |\baselineskip| is ignored.
%
% Double spacing is the default: the style uses
% the \@doubleleading factor, defined above.
%
% \begin{macrocode}
\renewcommand\baselinestretch{\@tightleading}%
% \end{macrocode}
% \end{macro}
%
% \begin{macro}{\tighten}
% The |\tighten| command merely resets the |\baselinestretch| to a
% smaller factor, resulting in single-column text that is more closely
% spaced. (This will always work.) Tightening the vertical spacing
% in the text results in output that is more attractive for distribution
% to colleagues who are primarily interested in reading the paper, as
% opposed to copy editing it. Double-spaced output for referees and
% copy editors is, however, the main objective of this style, hence
% double-spacing occurs by default. The same effect as |\tighten|
% can be achieved by using the |tighten| document style option.
%
% The |\tighten| command is intended for use in the preamble of the
% article.
%
% \begin{macrocode}
\newcommand\tighten{\def\baselinestretch{\@tightleading}}%
\newcommand\tightenlines{\tighten}%
% \end{macrocode}
% \end{macro}
%
% \begin{macro}{\singlespace}
% \begin{macro}{\doublespace}
% For authors who feel compelled to change between single and double
% spacing in the manuscript, |\singlespace| and |\doublespace| commands
% are provided. (Following recommendations of AAS Publications Board
% Subcommittee on Preprints.) These are no-ops in manuscript style.
%

% \end{macro}
% \end{macro}
%
% \begin{macro}{\sec@upcase}
% Upper case for sections (optional upper case items). These are
% created so that some headings can be toggled between mixed case and
% upper case readily.
% Headings that might be changed can be wrapped in the style file in
% |\sec@upcase{|\m{text}|}| constructs;
% the expansion of |\sec@upcase| is
% controlled here. It is |\relax| by default (mixed case heads), and
% can easily be changed to |\uppercase| if desired.
% If mixed case headings are wanted by the editor, authors {\em must}
% supply mixed case text, although this is what authors should be doing
% anyway.
% (Mixed can be converted to upper,
% but the reverse transformation cannot be automated.)
%
% \begin{macrocode}
% \end{macrocode}
% \end{macro}
%
% \begin{macro}{\parskip}
% \begin{macro}{\parindent}
% |\parskip| gives extra vertical space between paragraphs and
% |\parindent| is the width of the paragraph indentation. The value
% of |\parindent| depends on whether we are in two column mode.
% \begin{macrocode}
\setlength\parskip{1.5ex}%
\setlength\parindent{2em}%
% \end{macrocode}
% \end{macro}
% \end{macro}
%
% \begin{macro}{\smallskipamount}
% \begin{macro}{\medskipamount}
% \begin{macro}{\bigskipamount}

% give the following command in the document preamble:
% \begin{verbatim}
% \eqsecnum

% The preferred way is to call |eqsecnum| as a
% document class option:
% \begin{verbatim}
% \documentclass[eqsecnum]{aastex}
% \end{verbatim}
% \begin{macrocode}
\def\eqsecnum{%

%
% \subsection{Data Commands}%
%
% There are some obvious style-dependent parameters and formatting
% instructions in this file. The object has been to keep the author
% commands (the user interface, if you will) society-, journal-, and
% style-independent, while the style-specific parameters and commands
% are kept below that level.
%
% \subsubsection{Article Attributes}%
%
% \begin{macro}{\@journalname}

%
% Journal and article identification information is established by the
% editorial staff. The following macros are used by personnel at the
% editorial office to annotate/record slug-line data and should be
% included in the manuscript preamble, i.e., before the \LaTeX\
% |\begin{document}|.
% All they do is globally define other \TeX\ control sequences that are
% used by other macros at a later time.
% \begin{verbatim}
% \received{<receipt date>}
% \revised{<revision date>}
% \accepted{<acceptance date>}

% \subsubsection{Receipt and Acceptance Dates}%
% Editorial offices like to have receipt and acceptance dates on the

% The current practice is to require the author

% \subsubsection{Title, Author, etc.}\label{sec-preamble}%
% Title and author identification is by way of standard \LaTeX\ commands
% |\title| and |\author|.
% The authors' principal affiliation is specified with a separate macro |\affil|.
% Each |\author| command should be followed by its own |\affil| (or address).
%
% Authors often have affiliations above and beyond their main employer,
% and these are specified with the |\altaffilmark| and |\altaffiltext|
% commands.
% These commands behave like the |\footnotemark| and |\footnotetext|
% commands
% of \LaTeX.
% |\altaffilmark| is appended to author's names in the |\author| lists,
% and generates the superscript identification numbers.
% The text for the individual alternate affiliations is generated by the
% |\altaffiltext| command. It is up to the author to make sure that the
% |\altaffilmark| numbers attached to authors' names correspond to the
% correct alternate affiliation.
%
% The following commands may appear in the title block,
% with the |\title| command appearing exactly once, and
% all others appearing as many times as needed:
% \begin{verbatim}
% \title{<lucid text>}
% \author{<name(s)>}
% \authoraddr{<author's postal address>}% Deprecated (V5.0) in favor of \affil
% \email{<author's e-mail address>}

% \begin{macro}{\email}
% \begin{macro}{\affil}
% \begin{macro}{\altaffilmark}
% \begin{macro}{\altaffiltext}
% \begin{macro}{\and}
% The title block commands simply queue up the
% given tokens into the appropriate control sequence.

% The |\email| command has one meaning until the titlepage
% is set, then acquires a different meaning, appropriate for text use.

% \subsubsection{Automatically Triggering the Title}%
% In order to accomodate the many different formatting options
% for the title page, it is best for the user to
% present the title block and then to
% invoke the |\maketitle| command explicitly.
%
% The custom in V4.0 documents has been to give
% the commands of the title block
% as if they formatted the given material immediately---which they did.
% But this defies the \LaTeX\ markup scheme in which those commands
% are expected to act like ``data'' commands: they are legal
% in the preamble (before |\begin{document}|).
%
% Coupled with the need to automatically switch between
% one- and two-column page grids, it would be best if the
% title block commands were to return to their nature
% as ``data'' commands.
%
% An \aastex\ document will therefore begin with its
% |\begin{document}| declaration and its title block
% (which could legally appear in the preamble), followed
% by an optional |\maketitle| command, succeeded by
% optional |\tableofcontents| and similar commands,
% succeeded by the body of the article, which
% may begin with a sectioning command like |\section|,
% or may even begin with paragraph text.
%
% In order to trigger at the start of paragraph text, we
% install a hook into |\everypar|. This may fail under some
% circumstances because of the violent way \LaTeX\ handles
% this token register. (We hope for the best.)
%
% Given that the abstract is formatted as part of the
% title page, it, too, must have the status of a
% data command. However, its syntax as a \LaTeX\ environment
% prevents a simple approach using |\appdef|.
% Instead, we temporarily endow the |abstract|
% environment with the ability to set type.
%
% The procedure |\everypar@hook| takes advantage
% of a trick for returning to vertical mode, effectively
% aborting the nascent paragraph. The only trace thereof
% in the vertical list being the |\parskip| glue.

% \subsubsection{Bibliography}%
% For the time being, I don't think
% it would be a good idea to force an implementation based on BibTeX,
% although I'll prepare for that eventuality by using the constructs and
% general ideas of the \LaTeX\ |thebibliography| environment.
% Adjustments have been made so that the |\cite|--|\bibitem| mechanism
% can be used to cite references symbolically while maintaining proper
% citation syntax within the paper; the author must create the citation
% label for each reference in proper journal format in the |\bibitem|
% command.
% \begin{verbatim}
% \begin{thebibliography}
% \bibitem[label]{<texttag>}
% \reference <bibliographic data>
% \end{thebibliography}
% \end{verbatim}
%
% Observe that the bibliographic data supplied by the author must also
% conform to the standards of the journal. I have elected not to burden
% authors with tedious \LaTeX\ commands which would require many curly
% braces to delimit the bibliographic fields because many of the
% journals I have targeted in this project have agreed to reduce
% typographic overhead (bolding, italicizing, etc.) in reference lists.
% (See Abt's editorial in ApJ 357.)
% It is the responsibility of the author to get these fields in the
% proper order with the correct punctuation; the information will be
% typeset as is, i.e., in roman with no size or style changes.
%
% Macros are provided for many of the oft-referenced journals so that
% authors may use the \LaTeX\ names rather than having to look up a
% particular journal's
% specific abbreviation. In principle, all the journals should be using
% the same abbreviations, too, but I anticipate some changes in the
% specific abbreviations before a set is finally settled on. As long as
% these macros are kept up to date, authors need not be concerned about
% such editorial changes.
%
% Corresponding with the non-BibTeX references environment and
% |\reference| command for the reference list is the |\markcite|
% command.
% This can be used to identify in-text citations; in this case, the
% author provides the actual citation text as opposed to the symbolic
% tag.
% The use of this is encouraged, even for journals where no special
% formatting of citation call-outs is required; it is crucial for the
% future use of on-line browsers.
%
% Note: |\markcite| is deprecated (V5.0) and has been eliminated.

% \subsubsection{Plano Tables}%
%
% Plano tables are camera-ready pages that are included in a typeset
% article the same way as line drawings, graphs, and other camera-ready
% art, i.e., as ``planographic'' figures. There are desirable
% properties for a formatter to have that are somewhat above and beyond
% \LaTeX\'s |tabular| environment that would facilitate the creation of
% such tables.
% Among these are breaking long tables across pages, using footnotes
% in a table, specifying comments and references for tables, etc.
%
% Note for V5.0:
% Plano tables are no longer supported, but the capabilities of
% the |deluxetable| are still part of \aastex.
% What this means for the user is that all tables should be coded
% in \LaTeX, whether using the standard \LaTeX\ mechanisms or
% using the enhancements of |deluxetable|, however, the
% appearance of the table in the printed journal will be under the control
% of the publisher and not the author.
%
% Style Note:
% ApJ ``standard'' widths for tables are 21 and 42 picas, which are the
% widths of single and double columns in the journal. For wide tables,
% any width less than 42 is acceptable, although using widths of 30pc
% and up will result in better appearance when centering. Landscape
% orientation is acceptable, and I have provided the pseudo-option
% |\ptlandscape| that resets the page dimensions; the author is still
% responsible for running the local DVI translator with the proper
% parameters so that landscape pages emerge from the laser printer.
%
% Style Note:
% AJ has no ``standard'' widths for camera-ready tables,
% they simply need to be narrower than the page.
% Landscape orientation is acceptable,
% and I have provided the pseudo-option |\ptlandscape| that resets the
% page dimensions; the author is still responsible for running the
% local DVI translator with the proper parameters so that landscape
% pages actually emerge from the laser printer.
%
% What follows was inspired by supertab.sty by Theo Jurriens, 1988.
%
% We define descriptive markup for table elements.
% Observe that the formatting is embedded in the macro definitions
% so that the author doesn't need to be concerned about stylistic
% nuances.

% \begin{macro}{\tablevspace}
% \begin{macro}{\tablebreak}
% Author markup commands for planotable environment line breaks.
%
% In version 4.0, it was necessary to use |\nl| or |\nextline| instead
% of |\\| and to employ an alternative mechanism for introducing extra
% vertical space:
% \begin{verbatim}
% \nl == \nextline Used in place of LaTeX's \\
% \tablevspace{<dimen>}
% \tablebreak
% \end{verbatim}
%
% In this version of \aastex\, the user can simply employ \LaTeX's |\\|
% as per usual.
% The user can supply an optional argument to govern the vertical
% spacing as usual, and the *-form prevents a pagebreak.
%
% Consequently, |\nl|, |\nextline|, and |\tablevspace| are now deprecated.
%
% Note that there is a significant problem with the |\tablevspace| command that
% recommends against its use:
% if the table splits at that point, the extra vertical space
% will fall at the top of the next page's table.
% \begin{macrocode}
\newcommand\tablevspace[1]{\substitute@command\tablevspace\\[#1]}%
% \end{macrocode}
% In order to force a |deluxetable| to split (over pages), the user
% gives the |\tablebreak| command.
%
% Art says: As a means of controlling page breaks,
% I prefer to see the user employ the *-form of the
% row terminator |\\| to prevent the indicated line
% from splitting from the next line.
% Besides, there is a drawback in using |\tablebreak|, namely
% that it is syntactically different from |\\|, and
% unlike any extant \LaTeX\ capability.
% The ``\LaTeX\ way'' of forcing a page break would be
% to use the |\pagebreak| or |\newpage| commands.
% So I deprecate |\tablebreak|.

%

% journals; the author can use these markup tags without being concerned
% about the exact form of the journal abbreviation, or its formatting.
% It is up to the keeper of the macros to make sure the macros expand
% to the proper text. If macro package writers agree to all use the
% same TeX command name, authors only have to remember one thing, and
% the style file will take care of editorial preferences. This also
% applies when a single journal decides to revamp its abbreviating
% scheme, as happened with the ApJ (Abt 1991).

% we need have no concerns about being taken to task by the purity police.
%
% Implementation note: we use herein the |\count@| scratch register.

% \begin{macro}{\anchor}
% Syntax: |\anchor|\arg{href}\arg{text}.
%
% A general-purpose hypertext link tag, using the parlance of
% the HTML element |<<A>>| (anchor).
% |<href>| is a \emph{full} URI, including the |scheme:| designator
% and may be active in some sort of hyperref-savvy system;
% for now it has no semantic.
% The |<text>| argument is the copy to set in the document,
% much like the content of the HTML |<<A>>| element.

\newcommand\anchor[2]{#2}%
% \end{macrocode}
% \end{macro}
%
% \begin{macro}{\url}
% Syntax: |\url|\oarg{href}\arg{text}.
%
% We provide |\url| with the |<href>| as an optional argument,
% to support the degenerate case where an author wishes to express a URL in the text.
% In that case, |<href>|\({}={}\)|<text>|.
% If the author supplies both arguments, this command looks like an alias for |\anchor|.
% \begin{macrocode}

%
% This markup will also permit production software at the Press
% to make |mailto:| links, etc., in online products.
% |<address>| should \emph{not} contain the |mailto:| scheme designator.
%
% In general text, |\email{foo@bar}| produces |\textt{mailto:foo@bar}|.
% The |\email| command is also used in the author lists;
% |\authoremail| is deprecated.
%

% Syntax: |\objectname|\oarg{catalog ID}\arg{text}.
%
% Celestial objects can and should be identified by the author to facilitate
% post-processing of articles by the astronomical catalog databases.
% At the moment, this is done by eye, although when articles contain these
% marks, the Press could pass along a list of `objects in article'
% to database personnel. Obviously, more sophisticated technical solutions
% are possible.
%
% In the future, software could construct queries to those databases in the
% online editions, hence it may be useful for the author to supply a catalog identifier.
% We may choose to suppress the |<catalog ID>| argument in the
% documentation in the near term, since we don't have an architecture
% and a nomenclature for linking to them at this point.

%
% \section{Programming Conventions}%
% In writing the above code, I cleave to certain conventions, noted
% here.
% My goal in explaining them is to encourage others maintaining this
% body of code to consider following them as well.
% The benefits are twofold:
% Some of the coding conventions aim to avoid programming pitfalls;
% following them reduces maintenance costs.
% Others make the code easier to read; following these eases the
% process of understanding how the code works.
%
% And, for my part, I prefer to read code of this type.
%
% \subsection{Whitespace Conventions}%
% Exactly where code lines break and indent, and where additional
% whitespace is inserted is explained here.
% \begin{itemize}
% \item
% Each new macro definition or register assignment begins a new line.
% Therefore, |\def|, |\newcommand|, and their ilk will start in column
% 1.
% \item
% Code is indented one space for each level of nesting within braces
% |{}|.
% \item
% Likewise, if possible, for |\if...| and matching |\fi|.
% \item
% However, the closing brace or |\fi| is outdented by one so that it
% falls
% at the same level of indentation as its matching brace or |\if|,
% and it appears alone on its line.
% \item
% Use of the |tab| character is deprecated
% (tabs are not standardized across all applications and operating
% systems).
% \item
% Lines of code are limited to 72 characters.
% I follow this convention mostly to ease the transmission of files
% via email (a deprecated practice) and to accomodate people with
% small monitors.
% But |ltxdoc| output looks better with the shorter lines, too.
% \item
% Extraneous whitespace is avoided by using the comment character |%|.
% In most cases, if falling at the end of a line of code,
% a brace will be immediately followed by a comment character,
% as will the macro parameter |#1| and any one-letter control sequence,
% like |\\|.
% \end{itemize}
% These conventions taken together are illustrated by the following:
% \begin{verbatim}
%\def\prepdef#1#2{%
% \@ifxundefined#1{\toks@{}}{\toks@\expandafter{#1}}%
% \toks@ii{#2}%
% \edef#1{\the\toks@ii\the\toks@}%
%}%
% \end{verbatim}
% In the above, the definition of |\prepdef| would not fit on a single
% line,
% and required breaking. The first and last lines have matching braces,
% and are a the same level of indentation, with the last line containing
% a single brace.
%
% Each of the three intervening lines has balanced braces and is
% indented by one space. Each line that would otherwise end in a single
% brace character is terminated by a comment character.
%
% Some coders rely on the fact that a space character seen by \TeX's
% scanner while in vertical mode is a no-op.
% Be that as it may, I eliminate them unless actually intentional.
%
% \subsection{Conventions For Procedures}%
% Here are some of my preferences when writing procedures:
% \begin{itemize}
%
% \item
% I dislike defining a macro within another macro, especially when the
% pattern part is non-nil.
% You know, you are not saving much space in |mem| when you do this,
% right?
% You do save space in the hash table and the string pool, though.
% On the other hand, we are not dealing with small \TeX\ engines
% anymore; Team \LaTeX\ has made sure of this.
%
% \item
% If two or more macros have very similar replacement parts, consider
% layering.
%
% \item
% Macros may perform parsing, may maintain tokens or registers, or may
% set type (produce marks). I try to avoid combining the three functions
% in a single macro.
%
% \item
% When a procedure both does assignments and sets type, I try to have a
% clean separations between the two activities. Try to avoid:
% \begin{verbatim}
% \vskip10pt
% \parindent=0pt
% \leavevmode
% \end{verbatim}
%
% \item
% The Boolean calculus (cf. |\@ifx|)
% is very useful and produces code that executes nicely.
% Using it also helps avoid your having to debug problems where
% |\if...| and |\fi| are not properly balanced
% (a nightmare in case you didn't already experience it).
%
% \end{itemize}
%
% \subsection{Conventions For \LaTeX}%
% Team \LaTeX\ make certain recommendations in \file{clsguide.tex}.
% Ones that I particularly pay attention to are:
% \begin{itemize}
%
% \item
% For the sake of ``color safety'',
% use |\sbox| rather than |\setbox|, |\mbox| rather than |\hbox|, and
% |\parbox| or |minipage| rather than |\vbox|.
%
% \item
% Use |\newcommand| and |\newenvironment| to declare user-level commands
% and environments. Avoid the idiom |\def\foo|, |\def\endfoo| to define
% an environment.
% Ideally, all user-level markup could be extracted from the
% document class by grepping on |\newcommand| and |\newenvironment|.
%
% \item
% Prefer to use |\setlength| to assign registers.
%
% \end{itemize}
% I cannot help but notice that much of the code of \LaTeX\ itself fails
% to comply with many of the coding recommendations of Team \LaTeX.
%
%
% \section{Yet to do}%
% The following work is considered for the release of the \aastex\ 5.0
% package:
% \begin{description}
%
% \item[dot accents]
% Augment |\dot| and |\ddot| with |\dddot| and |\ddddot|.
%
% \item[Posters]
% Andrea wants to do posters. Ref best practices list. Sample document?
%
% \item[BibTeX]
% Support for BibTeX-generated bibliographies.
% Not a problem if using |thebibliography| and |\bibitem|.
% Hoguvain and Berend have written a \file{astrobib.bst}.
%
% \item[Landscape tables]
% Automatically rotate landscape tables if supported by output device.
% User may specify \cmd\rotate in the preamble of |deluxetable|.
% Works for any DVI translator targetting a PostScript printer.
%
% This command will be used in the pseudopreamble of deluxetable to create
% a turnpage (broadside) table in the midst of an upright (portrait) article.
% Implementation will be dependent on authors having a PostScript print engine.
%
% The |\rotate| command is implemented syntactically, but not semantically.
%
% \item[Two-column preprint formatting]
% Automatically put text in 2-col, appendices in 1-col, references in
% 2-col, obviating the user's need to insert markup. Done.
%
% If using native \LaTeX, all float types are supported, columns are not
% balanced, and the page ends.
%
% If using |multicol|, only full-page floats are supported, columns
% balance, and pages do not break.
%
% \item[Table autoplacement]
% Possibly support automatically placing tables as follows:
% less than 20pc width---single column,
% up to 44pc width---full width,
% over 44pc width---landscape.
%
% \item[tighten]
% Class option |tighten| and commands |\doublespace|, |\singlespace| are noops in
% |manuscript| substyle. In others, what should be done?
%
% \item[documentstyle]
% What should happen to a compatibility mode document?
% Wouldn't we have to support the exact same document style options?
%
% \item[substyle names]
% Should we keep the old names or use the new ones?
%
% \item[FIXME]
% Resolve all the remaining notes.
%
% \item[Line lengths]
% Source lines should be no loonger than 72 characters. Done.
% But re-check.
%
% \item[Testing]
% In particular, the |\@ptabularcr| code is new,
% but I have done some testing.
%
% \item[Distribution]
% Why not make this class a supported \LaTeX\ oackage?
% It would go in: |CTAN:/macros/latex/contrib/supported|.
%
% \item[Macro names verbatim]
% Use |\cmd{\foo}| when the control sequence name
% appears in a moving argument.
% Use |\cs{foo}| when the name involves non-alpha characters.
%
% \item[Changes from 4.0]
% It would be good to have a section in the users guide
% called ``Changes from 4.0''.
% Summarizing
% the new markup commands,
% the removed markup commands,
% any alteration in formatting,
% etc.
%
% \item[Deprecated features list]
% To add to user documentation.
%
% \item[ltxdoc stuff]
% |\begin{environment}|, |\generate|
%
% \item[Best practices list]
% To add to user documentation.
% \begin{itemize}
% \item How to code celestial coordinates.
% \item How to specify object names (+,-).
% \item How to include figures.
% \item How to rotate tables.
% \item |\ge|, |\le| exist---use them!
% \item Don't include gigantic macro lists---please include only the ones you actually use.
% \item |\newcommand| is recommended; please avoid |\def|.
% \item Ionization potentials?
% \end{itemize}
%
% \item
% Natbib commands in user guide.
%
% \end{description}
%
% \section{Recently Done}%
%
% \begin{description}
%
% \item
% We have to say proactively that plano tables aren't accepted anymore,
% and not just remove those words from the AASTeX user guide.
% That's why the |apjpt| and |aj_pt| substyles are removed from v4.1.
% Done 9113.
%
% \item
% \cmd\SGMLcite. (CB): Deprecated in favor of <TT>\cite*. Unimplemented.
% \item
% \cmd\slantfrac reimplemented with \cmd\case. Done 9113.
%
% \item[Deprecate commands]
% Deprecate |\nl|, |\nextline|, |\tablevspace|, and |\tablebreak|. Done 9113.
%
% \item[URL commands]
% Functionality covered by |hyperref| package.
% Syntax: |\anchor|\arg{HREF}\arg{text}.
% Syntax: |\url|\oarg{URL-specification}\arg{text}.
% Syntax: |\email|\arg{address}.
% Ref: \file{url.sty} in |/contrib/other/misc|. \file{hyperref.sty} in |/contrib/supported/hyperref|.
% Done 9113.
%
% \item[Celestial objects]
% Syntax: |\objectname|\oarg{catalogID}\arg{text}. Done 9113.
%
% \item[\texttt{slantfrac}]
% \texttt{slantfrac} to be deprecated. |\onehalf| and friends to be
% implemented with |\frac|. Done 9113.
%
% \item[Extensions to \texttt{cite}]
% Support multiple citations in natural language. Ref email from Anton. Done with |natbib|.
%
% \item[\texttt{natbib}]
% I incorporated |natbib| into \aastex\ as a vehicle for the expanded
% citation functionality. |natbib| seems the right choice because
% it is a part of |latex/contrib/supported|, is well thought out and implemented
% and because it provided more than enough functionality, albeit
% via different syntax.
%
% \item[\texttt{amsmath}]
% The |amsmath| package is the successor to the \LaTeX2.09 |amssymb| package.
% I have incorporated it into \aastex\ (that is, it is automatically loaded),
% making it a constant part of \aastex\ rather than an option.
%
% The |amsmath| package is a part of |latex/packages/|, so it is an
% ``annointed'' package---much more blessed than even the
% |latex/contrib/supported| stuff. I have no hesitation about
% mandating its use.
%
% \item[Unknown Symbols]
% The following control sequence names cause \LaTeX\ to complain:
% |\lhd|, |\rhd|, |\unlhd|, |\unrhd|, |\sqsubset|, |\sqsupset|,
% |\Join|, |\leadsto|, |\Box|, |\Diamond|, |\mho|.
% The message seen is:
% \begin{verbatim}
% ! LaTeX Error: Command \lhd not provided in base LaTeX2e.
% \end{verbatim}
% This problem is now fixed (9113).
%
% \item[UCPress administrative markup]
% Syntax: \cmd\journal\arg{ID}, \cmd\SGML\arg{text}, \cmd\SGMLentity\arg{text}.
% No production. Not documented in user guide. Done 9113.
%
% \item[Evan's Markup]
% Done 9113.
% \begin{itemize}
% \item
% \cmd\journal\arg{ApJ},
% \cmd\articleID\arg{number},

%
% \item[Evan's Points]
% \begin{itemize}
% \item
% \cmd\shorttitle\arg{text} and \cmd\shortauthors\arg{text}

% \item
% \cmd\anchor is \cmd\url
% \item
% No plates anymore.
% \item
% Turnpage figures are a requirement.
% \end{itemize}
%
% \end{description}
%
% \section{User Documentation and Sample Documents}%
% User documentation for \aastex\ is the file \file{aasguide.tex},
% generated by the {\sc docstrip} module following this section.
%
% Note:
% This file requires the \file{aastex.cls} document class itself,
% thereby lengthening the bootstrap process.
% The requirement enters in the section documenting
% the text entities defined by the class (see key |spec.symbols|).
%
% Sample files for this distribution of \aastex\ include
% \begin{itemize}
% \item
% |sample.tex| is an \aastex\ tutorial paper with a fairly complete
% set of markup.
% \item
% \item
% |table.tex| is a sample \aastex\ table with complex column headings.
% \end{itemize}%
%
% Since the user documentation and sample files are not heavily commented,

\section{Introduction}
The American Astronomical Society (AAS) has developed a markup package to assist authors in preparing manuscripts intended for submission to AAS-affiliated journals, as well as to other journals that will accept \aastex\ manuscripts.
The most important aspect of the \aastex\
package is that it defines the set of commands, or markup,
that can be used to identify the structural elements of papers.
When articles are marked up using this set of standard commands,
they may then be submitted electronically to the editorial
offices and fed into the electronic production of the journals.
This guide contains basic instructions for creating
manuscripts using the \aastex\ markup package.
Authors are expected to be familiar with the editorial
requirements of the journals so that they can make
appropriate submissions; they should also have a basic
knowledge of \LaTeX---for instance, knowing
how to set up equations using \LaTeX\ commands.
A number of useful publications about \LaTeX\ (and \TeX) are listed in
the reference section of this guide.
{\em Authors who wish to submit papers electronically to the ApJ, AJ, or PASP are strongly encouraged use the \aastex\ markup package as described in this guide.}
% \end{macrocode}
%
% Package context
% \begin{macrocode}
\section{\aastex\ Article Markup}
This section describes the commands in the \aastex\
package that an author might enter in a manuscript that is being
prepared for electronic submission to one of the journals.
The commands will be described in roughly the same order as they
would appear in a manuscript.
The reader will also find it helpful to examine the
sample files that are distributed with the package and to consult the
information available on the AASTeX Web site located at \aastexhome.
Authors are also reminded to review the instructions to authors and electronic
submissions guidelines for the specific journals to which they submit
their papers.
\subsection{Preamble}\label{sec-preamble}
In \LaTeX\ manuscripts, the preamble is that portion of the file before
the \verb"\begin{document}" command.
\subsubsection{Getting Started}
The first piece of markup in the manuscript declares the
overall style of the document. Any commands that appear before this
markup will be ignored.
\begin{quote}\index{documentclass@\verb`\documentclass`}
\begin{verbatim}
\documentclass{aastex}
\end{verbatim}
\end{quote}
This specifies the document class as \texttt{aastex} with the
default style (|manuscript|).
The paper copy produced by this style file will be double spaced.
Any tables included in the main body of the manuscript will also be
double spaced.
Other substyles are available. They are discussed in \S~\ref{styles}.
\subsubsection{Defining New Commands}
\aastex\ allows authors to define their own commands with
\LaTeX's \verb"\newcommand".
(Authors should not use the plain \TeX\ \verb"\def" command in
AAS journal submissions.)
Authors' \verb"\newcommand" definitions must be placed in the
document preamble.
In general, author-defined commands that are
abbreviations or shorthands, for instance,
\begin{quote}
\begin{verbatim}
\newcommand{\lte}{local thermodynamic
equilibrium}
\end{verbatim}
\end{quote}
, are acceptable and can be easily handled
by journal offices and publishers during data conversion.
However, abbreviations that attempt to define new symbols by using
\LaTeX\ commands for repositioning text tend to
cause problems in the publication process and should be avoided.
In particular, author-defined commands that use any of the commands
listed below are apt to cause problems during data conversion.
\begin{quote}
\verb"\hskip", \verb"\vskip",
\verb"\raise", \verb"\raisebox",
\verb"\lower", \verb"\rlap",
\verb"\kern", \verb"\lineskip",
\verb"\char", \verb"\mathchar",
\verb"\mathcode", \verb"\buildref",
\verb"\mathrel", \verb"\baselineskip"
\end{quote}
Consequently, authors are strongly discouraged from
using them.
Extra symbols are defined for \aastex,
some specifically for an astronomical context, others more
broadly used in math and physics.
In particular, the AMS has additional symbol fonts that are
available in a standard \LaTeX\ package (\verb"amssymb").
All of these symbols are depicted in the additional symbosl tables
supplied with the package and on the \aastex\ Web site.
Before defining a new symbol command,
authors are advised to consult these tables to see whether the
symbol they need already exists. If it does, they should use the
corresponding markup command.
Authors should \emph{not} redefine existing command names.
When one of these commands is encountered in an electronic
manuscript submitted to a journal, an author's redefinition will
be ignored and the originally-defined command used.
\subsubsection{Editorial Information}
A number of markup commands are available for
editorial office use in recording the publication history
for each manuscript.
These commands should be used by
the editorial and production offices only.
\begin{quote}
\begin{verbatim}
\received{<receipt date>}
\revised{<revision date>}
\accepted{<acceptance date>}
\ccc{<code>}
\cpright{<type>}{<year>}
\end{verbatim}
\end{quote}
Copyright information should be specified with the commands \verb"\cpright"\
and \verb"\ccc". The type of copyright and the corresponding year
are given in \verb"\cpright". Valid copyright types are as follows.
\begin{quote}
\begin{tabular}{l@{\quad}p{1.8in}}
\tt AAS & Copyright has been assigned to the AAS\\
\tt ASP & Copyright has been assigned to the ASP\\
\tt PD & The article is in the public domain\\
\tt none & No copyright is claimed for the article
\end{tabular}
\end{quote}
The copyright type is case sensitive, so the type string must be
entered exactly as given above.
The Copyright Clearing Center code may be given in the \verb"\ccc"\
command. The code is taken as regular text, so any special characters,
notably ``\$,'' must be escaped as appropriate.
\subsubsection{Short Comment on Title Page}
Authors who wish to include a short remark on the title page,
such as the name and date of the journal to which an article
has been submitted, may do so with the following command.
\begin{quote}
\begin{verbatim}
\slugcomment{<text>}
\end{verbatim}
\end{quote}
In the
\texttt{manuscript} style,
these comments appear on the title page after the title and authors;
in the
\texttt{preprint} style,
they are placed at the upper right corner
of the title page.
\subsubsection{Running Heads}\label{shorthead}
Authors are invited to supply running head information using the
following commands.
\begin{quote}
\begin{verbatim}
\shorttitle{<text>}
\shortauthors{<text>}
\end{verbatim}
\end{quote}
Two different kinds of data are generally supplied in running heads.
The left head contains an author list, (last
names, possibly truncated as ``et al.''), while the right head
is an abbreviated form of the paper title. This running head
information will not appear on the \LaTeX-printed page but will be
passed through to copy editing staff
for inclusion in the published version.
Editors and publishers impose varying requirements
on the brevity of these data. A good rule of thumb is to limit the list
of authors to three or else use ``et al.,'' and to limit the
short form of the title to 40--45 characters.
The editors may choose to modify the author-supplied
running heads.
\subsection{Starting the Main Body}
The preamble is a control section.
None of the markup that appears in the preamble
actually typesets anything. The author must include a
\begin{quote}
\begin{verbatim}
\begin{document}
\end{verbatim}
\end{quote}
command to identify the beginning of the main, typeset
portion of the manuscript.
\subsection{Title and Author Information}
Authors should use the
\verb"\title"\
and \verb"\author"\ commands to specify title
and author information and the \verb"\affil" command
to indicate the author's primary affiliation.
Each \verb"\author"\
command
should be followed by a corresponding \verb"\affil"\
and optional \verb"\email"\ command.
\begin{quote}
\begin{verbatim}
\title{<text>}
\author{<name(s)>}
\affil{<affiliation>}
\affil{<address>}
\email{<e-mail address>}
\and
\end{verbatim}
\end{quote}
Line breaks may be inserted in the title
with the \verb"\\" command. (Long titles will
be broken automatically, so the \verb"\\" markup is not required.)
If the title is explicitly broken over several lines, the
preferred style for titles in AAS and ASP journals is the so-called
``inverted pyramid'' style. In this style, the longest line
is the first (or top) line, and each succeeding line is shorter.
The text of the title should be entered in mixed case;
it will be printed in upper case or mixed case according to
the style of the publication.
Footnotes are permissible in titles. Be careful to ensure that
alternate affiliations (see below) are properly numbered if a
footnote to the title is specified.
Authors' names should be entered in mixed case.
Names that appear together in the author list for authors who
have the same primary affiliation should be specified in a single
\verb"\author"\ command.
Each author group should be followed by
an \verb"\affil"\ command giving the principle
affiliation of those authors. Physical and postal address information
for the specified institution may be included with \verb"\affil".
The address can be broken over several lines using the
\verb"\\" command to indicate
the line breaks.
Usually, however, postal information will fit on one line.
When there is more than one \verb"\author"\ command, the final
one should be preceded by the \verb"\and"\ command.
Authors often have affiliations in addition to their principle employer.
These alternate affiliations may be specified with the \verb"\altaffilmark"\
and \verb"\altaffiltext"\
commands.
These behave like the \verb"\footnotemark"\
and |\footnotetext| commands of \LaTeX\ except that they do not take
optional arguments. \verb"\altaffilmark"\
is appended to authors' names in the \verb"\author"\
list and generates superscript identification numbers.
The text for the individual alternate affiliations is generated by the
\verb"\altaffiltext"\
command.
\begin{quote}
\begin{verbatim}
\altaffilmark{<key number(s)>}
\altaffiltext{<numerical key>}{<text>}
\end{verbatim}
\end{quote}
It is up to the author to make sure that
each \m{key number} in his or her \verb"\altaffilmark"\
matches the \m{numerical key} for
the corresponding \verb"\altaffiltext".
When there is a lengthy author list, all author names may be
specified in a single \verb"\author"\
command with affiliations
specified using the \verb"\altaffilmark"\ me\-chan\-ism.
In these cases, no \verb"\affil"\
commands are used, and in print, the
affiliations would all be listed in a footnote block at the bottom
of the title page.
\subsection{Abstract}
A paper's abstract should be marked with the
\texttt{abstract} environment.
\begin{quote}
\begin{verbatim}
\begin{abstract}
<abstract text>
\end{abstract}
\end{verbatim}
\end{quote}
If an author is using the \texttt{preprint2} style, and the abstract is too long to fit on the title page, the \texttt{longabstract} option may be used in the \texttt{documentclass} to break the abstract to a new page.
\noindent
%\begin{quote}
\begin{verbatim}
\documentclass[preprint2,longabstract]{aastex}
\end{verbatim}
%\end{quote}
\noindent Note that authors should use the \texttt{longabstract} option only in \texttt{preprint2} mode and only when the abstract is too long to fit on the title page.
\subsection{Keywords}
Keywords, or subject headings, are accommodated
as a single piece of text.
\begin{quote}
\begin{verbatim}
\keywords{<text>}
\end{verbatim}
\end{quote}
If authors supply keywords, they must be delimited by whatever
punctuation is required by the journal.
They should be specified in alphabetical order.
The \verb"\keywords"\
command will print the proper leading text---``Keywords:,'' ``Subject headings:,'' etc.---according to journal style.
\subsection{Comments to Editors}
Authors may make notes or comments to the copy editor with the
\verb`\notetoeditor` command.
\begin{quote}
\begin{verbatim}
\notetoeditor{<text>}
\end{verbatim}
\end{quote}
This command behaves like a
footnote. Output to the printed page is produced only in the
\texttt{manuscript} style.
\subsection{Sections}
\aastex\ supports four levels of section headings.
\begin{quote}
\begin{verbatim}
\section{<heading>}
\subsection{<heading>}
\subsubsection{<heading>}
\paragraph{<heading>}
\end{verbatim}
\end{quote}
Section headings should be given in upper case or mixed case, depending
on the style of the journal.
Note that these commands delimit sections by marking the
\emph{beginning} of each section;
there are no separate commands to mark the ends.
\subsection{Figure and Table Placement} \label{place}
When preparing a manuscript for submission to an AAS journal, figures and tables do not generally need to be ``placed'' in the text of the
document where an author would like them to appear but
rather may simply follow the main body of the text.
However, authors may indicate to the editors the preferred placement of
these items by use of the \verb"\place*" commands.
\begin{quote}
\begin{verbatim}
\placetable{<key>}
\placefigure{<key>}
\end{verbatim}
\end{quote}
The \verb"\place*{"\m{key}\verb"}" commands are similar to the
\verb"\ref"
command in La\TeX\
and require corresponding \verb"\label"\
commands to link them to the
proper elements.
When used in the
\texttt{manuscript} style, the \verb"\place*"\ commands will print a short
message to the editor about figure or table placement.
In the other styles, nothing is printed.
\subsection{Acknowledgments}
\aastex\ supports an
\verb"\acknowledgments"%
\index{acknowledgments@\verb`\acknowledgments`} section.
\begin{quote}
\begin{verbatim}
\acknowledgments
<acknowledgments text>
\end{verbatim}
\end{quote}
In the \aastex\ styles, acknowledgments are set off from the
conclusion of the body with vertical space. Note the acknowledgments
command takes no arguments.
\subsection{Facilities}
To help organizations obtain information on the effectiveness of their
telescopes, the AAS has created a group of keywords for telescope
facilities. Using a common set of keywords will make searches for
this information significantly easier and more accurate.
In addition, the use of facility
keywords will be useful for linking papers that utilize the
same telescopes together within the framework of the Virtual Observatory.
A facilities keyword list is available through a
link at the AASTeX Web page, \aastexhome.
The facilities list should appear after the
acknowledgments section.
\begin{quote}
\begin{verbatim}
Facilities: \facility{<facility ID>},
\facility{<facility ID>},
\facility{<facility ID>}, ...
\end{verbatim}
\end{quote}
As part of the {\it facility ID} argument,
the author may also include
the name of the instrument in parentheses, e.g.
|\facility{HST(WFPC2)}| or |\facility{MMT(Blue channel spectrograph)}|.
There is no limit to the number of facility keywords
that may be included in a paper.
\subsection{Appendices}
When one or more appendices are needed in a paper, the point where the
main body text ends and the appendix begins should be marked
with the \verb"\appendix"\
command.
\begin{quote}
\begin{verbatim}
\section{<body section>}
\appendix
\section{<appendix section>}
\end{verbatim}
\end{quote}
The \verb"\appendix"\
command takes care of a number of internal
housekeeping concerns, such as identifying sections with letters
instead of numerals, and resetting the equation counter.
Note that the \verb"\appendix"\
command takes no arguments.
Sections in the appendix should be headed with \verb"\section"\
commands.
\subsection{Equations}
Display equations can be typeset in \LaTeX\ in a number of ways.
The following three are probably of greatest use in AASTeX.
\begin{quote}
\begin{verbatim}
\begin{displaymath}
\end{displaymath}
\begin{equation}
\end{equation}
\begin{eqnarray}
\end{eqnarray}
\end{verbatim}
\end{quote}
The
\texttt{displaymath} environment
will break out a single,
unnumbered formula. The \texttt{equation} environment does the same
thing except that the equation is
autonumbered by \LaTeX.
To set several formul\ae\ in which vertical alignment
is required, or to display a long equation across multiple lines, use the
\texttt{eqnarray} environment. Each line of the \texttt{eqnarray}
will be numbered
unless a \verb"\nonumber"\
command is inserted
before the equation line delimiter
(\verb"\\").
\LaTeX's equation counter is \emph{not} incremented when
\verb"\nonumber"\
is used.
Authors may occasionally wish to group related equations together and
identify them with letters appended to the equation number.
When this is desired, such related equations should still be set
in \texttt{equation} or \texttt{eqnarray} environments, whichever is
appropriate, and then grouped within
the \texttt{mathletters} environment.
\begin{quote}
\begin{verbatim}
\begin{mathletters}
<equation> or <eqnarray>
\end{mathletters}
\end{verbatim}
\end{quote}
It is possible to override \LaTeX's automatic numbering within the
\texttt{equation} or \texttt{eqnarray} environments using
\begin{quote}
\begin{verbatim}
\eqnum{<text>}
\end{verbatim}
\end{quote}
When \verb"\eqnum"\
is specified inside an \texttt{equation} environment
or on a particular equation within an \texttt{eqnarray}, the text
supplied as an argument to \verb"\eqnum"\
is used as the equation
identifier.
\LaTeX's equation counter is \emph{not} incremented when \verb"\eqnum"\
is used.
\verb"\eqnum"\
must be used \emph{inside} the math environment.
If, as a consequence of the use of \verb"\eqnum"\
or \verb"\nonumber",
\LaTeX's equation counter gets out of synch with the author's
intended sequence,
the counter may be reset to a particular value.
\begin{quote}
\begin{verbatim}
\setcounter{equation}{<number>}
\end{verbatim}
\end{quote}
The equation counter should be set to the number corresponding to the
last equation that was formatted; therefore, it is most appropriate for this
command to appear immediately after an \texttt{equation} or
\texttt{eqnarray} environment.
The command must be used
\emph{outside} the math environments.
The \texttt{eqsecnum} style file can also be used to modify the way equations
are numbered. See \S~\ref{styles} for details.
\subsection{Citations and Bibliography} \label{bibliography}
Two options are available for marking citations
and formatting reference lists: the standard \LaTeX\ \verb"thebibliography"\
environment, and the \aastex\ \verb"references"\ environment.
Authors are strongly encouraged to use \verb"thebibliography"\
in their electronic submissions.
Please note that the bibliographic data supplied by the author in
the reference list must conform to the standards of the journal.
Many of the journals that
accept \aastex\ agreed to reduce typographic overhead, bold, italic, etc.,
in reference lists \citep{Abt90}, and the AAS
has elected not to burden authors with tedious markup commands
to delimit the bibliographic fields. Instead, citations will be
typeset in roman with no size or style changes.
It is the responsibility of the author to
arrange the required bibliographic fields in the
proper order with the correct punctuation, according to journal
style.
\subsubsection{The {\tt thebibliography} Environment} \label{bib}
The preferred method for reference management is to use \LaTeX's
\texttt{thebibliography} environment, marking citations in the body
of the paper with
\verb"\citep"\ or \verb"\citet"\
and associating references with them using \verb"\bibitem".
The \verb"\cite"-\verb"\bibitem"\
mechanism associates citations and references symbolically
while maintaining proper citation syntax within the paper.
In the \verb"\bibitem"\
command, the author should specify citation data inside
square brackets and a citation key in curly braces
for each reference. (The |\bibitem| command is described
in detail in the next section.)
\noindent
%\begin{quote}
\begin{verbatim}
\begin{thebibliography}{<dummy>}
\bibitem[<cite data>]{<key>} <bibliographic data>
.
.
\end{thebibliography}
\end{verbatim}
%\end{quote}
\noindent Note that the argument \m{dummy} to the start command of the
environment is not
used in the \aastex\ package, but it is included to be consistent with the
syntax of standard \LaTeX. It is acceptable to simply insert an
empty pair of curly braces at the end of the \verb"\begin{thebibliography}"\
command.
\subsubsection{Specifying Bibliographic and Citation Information}\label{spec-bib-data}
\aastex\ uses the |natbib| package \citep{Daly98} for
citation management.
The |natbib| package re-implements \LaTeX's |\cite| command,
offering greater flexibility for managing citations in the
author-year form.
When using |natbib|, bibliographic data are defined
in |\bibitem| commands.
\noindent
%\begin{quote}
\begin{verbatim}
\bibitem[<author>(<year>)]{<key>}
<bibliographic data>
\end{verbatim}
%\end{quote}
\noindent
The square-bracketed argument of the |\bibitem|
contains the \m{author} portion of the citation
followed by the \m{year} set off in parentheses.
The parentheses are important---|natbib| uses them to
determine the year portion of the citation---so be sure to
include them.
The argument \m{key} in curly braces is the code name
by which the citation is referenced in the text.
When placing citations in the text, the author should use
either a |\citep| or a |\citet| command.
\begin{quote}
\begin{verbatim}
\citep{<key(s)>}
\citet{<key(s)>}
\end{verbatim}
\end{quote}
The |\citep| command produces a citation that is entirely
set off by parentheses, e.g.\ ``(Cox 1995),'' while |\citet| permits
the author's name to form part of the text, e.g.\ ``Cox (1995).''
The plain \LaTeX\ |\cite| command behaves like |\citet|.
The citation \m{key} must correspond to the \m{key} in a |\bibitem| command.
During processing, information from the square-bracketed argument of the
key's |\bibitem| is inserted in
the text at the location of the \verb"\cite"\ command.
Multiple citation keys are separated by commas, e.g.,
|\citep|\allowbreak
|{knuth84,|\allowbreak
|cox95,|\allowbreak
|lamport94}|.
|\citep| and |\citet| each take optional arguments that specify
extra text to be appended to the citation label. Text in the first
set of square brackets will appear before the cite while
text in the second set will appear after it.
For instance, |\citep[chap. 2]{jon90}|
would produce the citation ``(Jones et al., 1990, chap. 2),''
|\citep[see][]{jon90}| would produce ``(see Jones et al, 1990),'' and
|\citep[see][chap. 2]|\allowbreak|{jon90}| would print
``(see Jones et al., 1990, chap. 2).''
In addition, the * form of the
cite commands will print the full author list instead of the
abbreviated form.
The syntax discussed above should be sufficient for the
vast majority of cases; however, \aastex\
does use the full |natbib| implementation, so many more
syntax options are available. For details on
the full range of |natbib| citation options, see the section
on using |natbib| on the \aastex\ Web
site and the |natbib| package documentation.
It is not possible to use \verb"\bibitem"
within \aastex's \texttt{references} environment
(\S~\ref{refenv}),
nor will \verb"\cite"\ commands work properly in the main body
if \verb"\bibitem" commands are absent.
\subsubsection{The {\tt references} Environment}\label{refenv}
Some authors might prefer to enter citations directly
into the body of an article. If so, the |references| environment may be
used to format the reference list. The
\texttt{references} environment
simply sets off
the list of references and adjusts spacing parameters.
\begin{quote}
\begin{verbatim}
\begin{references}
\reference{<key>} <bibliographic data>
.
.
\end{references}
\end{verbatim}
\end{quote}
While the
\texttt{references} environment
remains supported in \aastex,
we anticipate that authors will prefer the stronger capabilities of
the standard \LaTeX\ |thebibliography| commands as extended by |natbib|.
\subsubsection{Abbreviations for Journal Names}
\aastex\ commands are available for many of the most--frequently-referenced
journals so that authors may use the markup rather than having
to look up a particular journal's abbreviation.
In principle, all the journals should be using the
same abbreviations, but it is fair to anticipate some changes in
the specific abbreviations before a system is finally settled on.
If authors use the journal macros, they need not worry about
changes to journal style governing abbreviations in citations.
A listing of the current abbreviation macros appears
in Table~\ref{journame}.
\begin{table}

\subsection{Figures}
\subsubsection{Electronic Art}
If an author wishes
to embed graphics in a manuscript, it is necessary that
the graphics files conform
to the Encapsulated PostScript (EPS) standard \citep{PLRM}. The
author must also have an appropriate DVI translator,
one that targets PostScript output devices. (Detailed information
on preparing and submitting electronic art is
available in the submissions instructions for the journals.)
Several commands are available for including EPS files
in \aastex\ manuscripts. They should be placed within the
\texttt{figure} environment.
\begin{quote}
\begin{verbatim}
\begin{figure}
\figurenum{<text>}
\epsscale{<num>}
\plotone{<epsfile>}
\plottwo{<epsfile>}{<epsfile>}
\caption{<text>}
\end{figure}
\end{verbatim}
\end{quote}
When \verb"\figurenum" is specified inside the {\tt figure} environment,
the text supplied as an argument to \verb"\figurenum" will be used as the
figure identifier.
\LaTeX's figure counter is \emph{not} incremented when \verb"\figurenum"
is used.
\verb"\figurenum" must be used \emph{inside} the {\tt figure} environment.
\verb"\plotone" inserts the graphic in the named EPS file,
scaled so that the horizontal
dimension fits the width of the body text;
the vertical dimension is scaled to maintain the aspect ratio.
\verb"\plottwo" inserts two plots next to each other.
Scale factors are determined automatically from information in the
EPS file.
The automatic scaling may be overridden with the command
\verb"\epsscale{<num>}", where \m{num} is a scaling factor
in decimal units, e.g., 0.80.
The |\plotone| and |\plottwo|
macros are invocations of the |graphicx|
|\includegraphics| command. In most instances, using
|\plotone| or |\plottwo| should work for placing
figures in \aastex\ documents. However, if more
flexibility is needed, the |\includegraphics| command
may be invoked directly. For instance, to rotate
an image by 90 degrees, use
\begin{quote}
\begin{verbatim}
\includegraphics[angle=90]{<epsfile>}
\end{verbatim}
\end{quote}
See the |graphicx| package documentation or the \aastex\ Web site for a
complete list of the available arguments to |\includegraphics|.
Authors are strongly encouraged to use |\plotone|, |\plottwo|, or |\includegraphics| to place their EPS figures. However, as of the current release, the old |\plotfiddle| macro from v4.0 has been reintroduced and may be used if the desired figure placement cannot be achieved with one of the methods above. The syntax of the command is
\begin{quote}
\begin{verbatim}
\plotfiddle{<epsfile>}{<vsize>}{<rot>}{<hsf>}
{<vsf>}{<htrans>}{<vtrans>}
\end{verbatim}
\end{quote}
where the arguments are
\begin{center}
\begin{tabular}{l@{\quad}p{2in}}
\tt epsfile & name of the EPS file \\
\tt vsize & vertical white space to allow for plot (\LaTeX\ dimension)\\
\tt rot & rotation angle (degrees)\\
\tt hsf & horizontal width of scaled figure (PS points)\\
\tt vsf & vertical height of scaled figure (PS points)\\
\tt htrans & horizontal translation (PS points)\\
\tt vtrans & vertical translation (PS points)\\
\end{tabular}
\end{center}
PostScript points are 1/72 inches, so an \m{htrans} of 72 moves
the graphic 1 inch to the right. Note that the \m{vtrans} argument is
discarded in the reimplented macro and is included only for
backward compatibility with \aastex\ v4.0.
\subsubsection{Figure Captions} \label{legends}
Regardless of whether an author includes electronic art in a manuscript, figure captions, or legends, should be provided. If art is included in the document, use the \verb"\caption"\ command within the \texttt{figure} environment. If electronic art is not included, figure captions may be grouped together at the end of the document using \verb"\figcaption".
\begin{quote}
\begin{verbatim}
\figcaption[<filename>]{<text>\label{<key>}}
\end{verbatim}
\end{quote}
The optional argument, \m{filename}, can be used to iden\-ti\-fy
the file for the corresponding figure;
\m{text} refers to the caption for that figure. The author
may provide a \verb"\label"\ with a unique \m{key} for cross-referencing
purposes.
When the \verb"\figcaption"\ command is used, the figure
identification label,
e.g., ``Figure 1,'' is generated automatically by the command itself, so
there is no need to key this information.
There is an upper limit of seven figure captions per page.
Footnotes are \emph{not} supported for figures.
\subsection{Tables} \label{tables}
There is support in the \aastex\ package for tables via two mechanisms:
\LaTeX's standard \texttt{table} environment,
and the
\texttt{deluxetable} environment, which allows for the formatting
of lengthy tabular material. Tables may be
marked up using either mechanism, although use of
\texttt{deluxetable} is preferred.
Authors should \emph{not} use the \LaTeX\
\texttt{tabbing} environment when preparing electronic
submissions.
\subsubsection{The \texttt{deluxetable} Environment} \label{dte}
Authors are encouraged to use the
\texttt{deluxetable} environment to format their tables since it automatically
handles many formatting tasks, including table numbering and insertion
of horizontal rules. It also provides mechanisms for breaking tables and
controlling width and vertical spacing that are unavailable in the \LaTeX\
\texttt{tabular} environment.
The \texttt{deluxetable} environment
is delimited by \LaTeX's familiar
\verb"\begin"\ and \verb"\end"\ constructs.
The content consists of preamble commands and table data,
the latter delimited by \verb"\startdata"\
and \verb"\enddata".
\begin{quote}
\begin{verbatim}
\begin{deluxetable}{<cols>}
<preamble commands>
\startdata
<table data>
\enddata
\end{deluxetable}
\end{verbatim}
\end{quote}
The argument \m{cols} specifies the justification for each col\-umn.
An alignment token, ``l,'' ``c,'' or ``r,'' is given for each column,
indicating flush left, centered, or flush right.
\subsubsection{Preamble to the \texttt{deluxetable}}%
There are several commands in the
\texttt{deluxetable} environment
that
must be given in the preamble.
\begin{quote}
\begin{verbatim}
\tabletypesize{<font size command>}
\rotate
\tablewidth{<dimen>}
\tablenum{<text>}
\tablecolumns{<num>}
\tablecaption{<text>\label{<key>}}
\tablehead{<text>}
\end{verbatim}
\end{quote}
If a table is too wide for the printed page, the font size of the table
can be cahnged with the \verb"\tabletypesize" command, which takes as
an argument one of the the font size change commands:
\verb"\small"\
(11pt), \verb"\footnotesize"\
(10pt), or
\verb"\scriptsize"\
(8pt).
To force a table to be set in landscape orientation,
use the \verb"\rotate"\ \label{cmd-rotate} command. Note that
most DVI previewers will not properly render rotated |deluxetable|
output, so in order to see what the table looks like,
it must be output to PostScript and viewed there.
The width of a deluxetable is defined by \verb"\tablewidth".
If this command is omitted, the default width is the width of the page.
The table can be set to its natural width by specifying
a dimension of \verb"0pt".
Long tables may have a natural width that is
different for each page. The natural width for each page will be
printed to the log file during processing.
Authors may then use this log information to
define a fixed table width in order to give the
table a more uniform appearance across pages.
It is possible to override \LaTeX's automatic numbering within the
\texttt{deluxetable} environment.
When \verb"\tablenum"\
is specified inside a \texttt{deluxetable}
preamble,
the text supplied as an argument to \verb"\tablenum"\
will be used as the
table identifier.
\LaTeX's equation counter is \emph{not} incremented when
\verb"\tablenum"\
is used.
The caption (actually, the title) of the table is specified
in \verb"\tablecaption".
The text of \verb"\tablecaption"\
should be brief;
explanatory notes should be specified in the end notes to the table
(see \S \ref{tabendnotes}
below). If the caption
does not appear
centered above the table after processing, then specify the width of
the table explicitly with the \verb"\tablewidth"\
command and rerun
\LaTeX\ on the file. If an author supplies a \verb"\label"\ for cross-referencing purposes, this, too, should be included in the \verb"\tablecaption".
Column headings are specified with \verb"\tablehead".
Within the \verb"\tablehead", each column heading should be given
in a \verb"\colhead", which will ensure that the heading
is centered
on the natural width of the column.
There should be a heading for each column so that there are as
many \verb"\colhead"\
commands in the \verb"\tablehead"\
as there
are data columns.
\begin{quote}
\begin{verbatim}
\tablehead{
\colhead{<heading>} & \colhead{<heading>}}
\end{verbatim}
\end{quote}
If more complicated column headings are required,
any valid \texttt{tabular} command that constitutes a proper
head line in a \LaTeX\ table may be used. For example, the
|\multicolumn| command below would create a table head with
text centered over five columns.
\begin{quote}
\begin{verbatim}
\multicolumn{5}{c}{<text>}
\end{verbatim}
\end{quote}
Consult \citet{Lamport} or \citet{Kopka99} for further details
on the available table commands.
The \verb"\tablecolumns{"\m{num}\verb"}" command
is necessary if an author has
multi-line column headings produced by \verb"\tablehead"\
or other \LaTeX\
commands and is using either the \verb"\cutinhead"\
or \verb"\sidehead"\
markup (see below). The \m{num} argument should be
set to the true number of columns in the
table. The command must come before the \verb"\startdata"\
command.
%It is possible that a complicated table heading will overflow
%the vertical space allotted for the table heading.
%The fraction of the page allocated
%for the table heading may be changed with \verb"\tableheadfrac".
%The \m{num} argument to \verb"\tableheadfrac"\
% should be the
%decimal fraction of the page used for heading information.
%The default value is 0.1, meaning that 10\% of the page height
%is reserved for the table heading. It should rarely be necessary
%to change this value.
\subsubsection{Content of the \texttt{deluxetable}}%
After the table title and column headings have been specified,
data rows can be entered.
Data rows are delimited with the \verb"\startdata"\
and \verb"\enddata"\ commands.
The end of each row is indicated with the standard \LaTeX\ \verb"\\" command.
Data cells within a row are separated with \& (ampersand) characters.
\begin{quote}
\begin{verbatim}
\startdata
<data line>\\
<cell>&<cell>&<cell>\\
<more data lines>\\
\enddata
\end{verbatim}
\end{quote}
Column alignment within the data columns can be adjusted with the \TeX\
\verb"\phantom{"\m{string}\verb"}" command,
where \m{string} can be any character, e.g., \verb"\phantom{$\arcmin$}".
A blank character of width \m{string} is then inserted in the table.
Four commands have been predefined for this purpose.
\begin{quote}
\begin{tabular}{l@{\quad}p{2in}}
{\verb"\phn"%
} & {phantom numeral 0-9}\\
{\verb"\phd"%
} & {phantom decimal point}\\
{\verb"\phs"%
} & {phantom $\pm$ sign}\\
{\verb"\phm{"\m{string}\verb"}"} & {generic phantom}\\
\end{tabular}
\end{quote}
Extra vertical space can be inserted between rows with an optional argument to the
\verb"\\" command.
\begin{quote}
\begin{verbatim}
\\[<dimen>]
\end{verbatim}
\end{quote}
The argument is a dimension
and may be specified in any units that are legitimate in \LaTeX.
In a table, it may happen that several rows of data are
associated with a single object or item.
Such logical groupings should not be broken across pages.
In these cases, the |\tablebreak| command may be used to force
a page break at the desired point.
\begin{quote}
\begin{verbatim}
<table row>\\
\tablebreak
<next table row>\\
\end{verbatim}
\end{quote}
This command can be used any time that the default |deluxetable| page
breaks need to be overridden.
Journals often require that table cells that contain no data
be explicitly marked. This is to differentiate such cells from
blank cells, which are frequently interpreted as implicitly
repeating the entry in the corresponding cell in the row preceding.
Table cells for which there are no data should contain
a \verb"\nodata"\
command.
\begin{quote}
\begin{verbatim}
\nodata
\end{verbatim}
\end{quote}
Within the |deluxetable| body, two kinds of special heads are
allowed, |\cutinhead| and |\sidehead|.
A cut-in head is a piece of text centered across the width
of the table. It is spaced above and below
from the data rows that precede and
follow it and will appear set off by rules in the \LaTeX\ output.
Similarly, the command for a side head produces a row spanning
the width of the table but with the text left justified.
\begin{quote}
\begin{verbatim}
\cutinhead{<text>}
\sidehead{<text>}
\end{verbatim}
\end{quote}
Table footnotes (more properly, table \emph{end notes})
may also be used in the \texttt{deluxetable} environment.
Their use is described in detail in \S \ref{tabendnotes}.
\subsubsection{The \texttt{table} Environment}
Authors may also compose tables using the \texttt{table} environment.
\begin{quote}
\begin{verbatim}
\begin{table}
\end{table}
\end{verbatim}
\end{quote}
The \texttt{table}\ environment
encloses not only the tabular
material but also any title or footnote information
associated with the table.
Titles, or captions, for tables are indicated with a |\caption|
command
\begin{quote}
\begin{verbatim}
\caption{<text>\label{<key>}}
\end{verbatim}
\end{quote}
A table label, e.g. ``Table 2,'' is generated automatically
by \verb"\caption".
The author
may provide a \verb"\label"\ in the caption with a unique \m{key}
for cross-referencing
purposes.
The table body should appear within the \texttt{tabular} environment.
\begin{quote}
\begin{verbatim}
\begin{tabular}{<cols>}
\end{tabular}
\end{verbatim}
\end{quote}
The alignment tokens in \m{cols} specify the justification for each column. The letters ``l,'' ``c,'' or ``r'' is given for each column,
indicating left, center, or right justification.
Consult \citet{Lamport} for details about using
the
\texttt{tabular} environment
to prepare tables.
Each \texttt{tabular} table must appear within a \texttt{table}
environment. There should be only one \texttt{tabular} table per
\texttt{table}
environment.
If the journal requests manuscripts with only one table per page,
the author may need to insert a \verb"\clearpage"\
command after especially short tables.
Use the |\tableline| command to insert horizontal rules in the
|tabular| environment.
\begin{quote}
\verb"\tableline"
\end{quote}
The use of vertical rules should be avoided.
As with the \texttt{deluxetable} environment, it
is possible to override \LaTeX's automatic numbering within the
\texttt{table} environment using \verb"\tablenum".
\verb"\tablenum"\
must be used \emph{inside} the \texttt{table}
environment.
\subsubsection{Table End Notes} \label{tabendnotes}
\aastex\ supports footnotes and end notes within tables;
this support applies to both the
\texttt{deluxetable} environment
and the standard \LaTeX\ \texttt{table} environment.
Footnotes for tables are usually identified by lowercase letters
rather than numbers. Use the |\tablenotemark| and |\tablenotetext|
commands to supply table footnotes.
As with \verb"\altaffilmark" and \verb"\altaffiltext", a note label,
usually a letter, is required.
\begin{quote}
\begin{verbatim}
\tablenotemark{<key letter(s)>}
\tablenotetext{<alpha key>}{<text>}
\end{verbatim}
\end{quote}
The \m{key letter} of the |\tablenotemark| should be the same as the
\m{alpha key} for the corresponding \m{text}.
It is the responsibility of the author to make the correspondence
correct.
Sometimes authors tabulate materials that have corresponding
references and may want to associate these references with the table.
Authors may also wish to append a short paragraph of explanatory
notes that pertain to the entire table. These elements should be
specified with the commands below.
\begin{quote}
\begin{verbatim}
\tablerefs{<reference list>}
\tablecomments{<text>}
\end{verbatim}
\end{quote}
The \verb"\tablenotetext", \verb"\tablecomments", and
\verb"\tablerefs" commands \emph{must}
be specified after the
\verb"\end{tabular}" or \verb"\enddata" and before
the closing \verb"\end{table}" or \verb"\end{deluxetable}".
\subsection{Supplemental Materials}
For many years now, authors have been taking advantage of the AAS journals'
ability to post supplemental materials with their papers in the electronic
editions. Even though each paper must stand on its own
scientifically without the supplements, these materials are reviewed in the
peer review process and should be included in initial manuscript
submissions. As with regular figures and tables, papers with online only
data must reference each electronic object in the main text
and include an explanation of what the reader will
find in the electronic edition.
The four most popular types of supplemental materials are
machine-readable tables, online color figures, online-only figures, and
animations. Please see each journal's Web site for details on
what types of supplemental materials are acceptable, how to
submit these materials, author tools for preparing them,
and their associated costs.
\subsubsection{Machine-readable Tables}
Online-only tables submitted to AAS journals are converted
to a machine-readable
format for presentation in the electronic edition.
Machine-readable tables have two
parts: the formatted ASCII data and a metadata header that provides
format, units, and short explanations of each column of data. This
structure is designed to provide maximum flexibility and ease of use
for readers who wish to further manipulate the data with their own
computer programs or with software like Excel.
For each machine-readable table, the author should include a short sample
version of the table in his or her \LaTeX\ submission. This sample version
will appear in the print edition as well as
in HTML in the electronic edition. The sample table should be
5 to 15 lines long. It should include a table note at the end
with text indicating that a machine-readable
version will be available in the electronic edition. For instance,
\begin{quote}
\begin{verbatim}
\tablecomments{Table 1 is
published in its entirety in
the electronic edition of
the Astrophysical Journal.
A portion is shown here
for guidance regarding its
form and content.}
\end{verbatim}
\end{quote}
Each example table must
be cited and numbered as if it were a fully printed table.
\subsubsection{Online Color Figures}
For some journals, authors may submit figures
that will appear in black and white in the
print edition of a journal but in color in the electronic edition.
In these cases, authors must submit separate black and white and RGB color
versions of each figure labelled according to the
file-naming conventions required for the publication.
For the benefit of print journal readers, figure captions should be written
with the color information placed inside parentheses,
for instance, ``The dotted
line (colored blue in electronic edition)
is the H$_o$ = 75 km s-1 Mpc-1 model,'' and should
include a note directing the reader to
``See the electronic edition of the Journal
for a color version of this figure.''
\subsubsection{Online-only Figures}
This feature is mainly useful for articles that contain large compendia
of identification charts and other supplemental graphic material that need not
be printed in full in the paper journal. Online-only figures are intended to
provide supplemental information that is not critical to the scientific
content of the article but that might nonetheless be of interest to the reader.
Online-only figures must be mentioned explicitly by number and appear
in correct numerical order in the body of the text. At least one figure
in a series must be displayed as an example figure for the print edition.
The caption should carry a message indicating that
more figures are available in the electronic edition---for instance,
``Plots for all sources are available in the electronic edition of the journal.''
Enough information must be included in the figure caption for readers of the
print edition to determine what is contained in the online-only figures.
\subsubsection{Animations}
Currently, only animations in the MPEG format are accepted by the AAS journals.
Authors must supply a still frame from the animation in EPS format marked
up like a regular figure that will serve as an example for the reader.
They should include text in the caption for the
still frame indicating that an animation is
available electronically. For instance,
``This figure is also available as an mpeg
animation in the electronic edition of the {\it Astrophysical Journal}.''
As with online-only figures, authors must include enough information in the
figure caption for readers of the print edition to determine what the
animation illustrates.
\subsection{Miscellaneous}
\subsubsection{Celestial Objects and Data Sets}
Authors who wish to have the most important objects in their paper
linked to a data center in the electronic edition may do so using the
\begin{quote}
\begin{verbatim}
\objectname[<catalog ID>]{<text>}
\end{verbatim}
\end{quote}
macro, or its alias |\object|.
The text contained in the required argument
will be printed in the paper and will serve as a link anchor
in the electronic edition. The catalog ID
given as an optional argument will be carried through as the identification
key in the link to a data center. Note that links will only
be activated if the name provided in the argument is recognized by a
participating data center. It is the author's responsibility to use the
correct identifier.
Similar markup is available for linking to data sets hosted
at participating data centers.
\begin{quote}
\begin{verbatim}
\dataset[<catalog ID>]{<text>}
\end{verbatim}
\end{quote}
In the paper, the text in the required argument will be
printed while the the catalog ID value will be passed through to form
links to data centers.
When an article contains |\object| or |\dataset| commands, the
publisher will be able to use the markup to
pass along a list of objects and data sets used in the
paper to database personnel. Software can then be used to construct links to
those databases.
Please check with each journal's Web site for instructions on how to
determine the object and data set identifiers, the location of
verifications tools, and information on where in the paper these
macros can best be used.
\subsubsection{Ionic Species and Chemical Bonds}
When discussing atomic species, ionization levels can be indicated
with the following command.
\begin{quote}
\begin{verbatim}
\ion{<element>}{<level>}
\end{verbatim}
\end{quote}
The ionization state is specified as the second argument
and should be given as a numeral.
For example, ``\ion{Ca}{3}'' would be marked up as \verb"\ion{Ca}{3}".
For single, double, and triple chemical bonds, use the following macros.
\begin{quote}
\begin{verbatim}
\sbond
\dbond
\tbond
\end{verbatim}
\end{quote}
\subsubsection{Fractions}
\aastex\ contains commands that permit authors to specify alternate
forms for fractions.
\LaTeX\ will set fractions in displayed math as built-up fractions;
however, it is sometimes desirable to use case fractions in
displayed equations.
In such instances, one should use \verb"\case"\
rather than \verb"\frac". Note, however, that authors submitting
manuscripts electronically to AAS journals
should generally find it unnecessary to use any markup other than the
standard \LaTeX\ \verb"\frac".
\begin{center}
\renewcommand{\arraystretch}{1.4}
\begin{tabular}{@{}llc@{}}
Built-up & \verb"\frac{1}{2}" & $\displaystyle\frac{1}{2}$ \\
Case & \verb"\case{1}{2}" & $\case{1}{2}$ \\
Shilled & \verb"1/2" & $1/2$ \\
\end{tabular}
\end{center}
\subsubsection{Astronomical Symbols}
As mentioned earlier, the \aastex\ package
contains a collection of assorted macros
for symbols and abbreviations specific to an astronomical context.
These are commonly useful and also somewhat difficult for authors
to produce themselves because fussy kerning is required.
See the symbols pages provided with the package distribution.
Most of these commands can be used in both running text and math. However,
\verb"\lesssim"\ and \verb"\gtrsim"\ can only be used in math mode.
\subsubsection{Hypertext Constructs}
The \verb"\anchor"\ \label{cmd-anchor} command is a general-purpose
hypertext link tag, associating \verb"<text>" in the manuscript with
the specified resource (\verb"<href>").
\begin{quote}
\begin{verbatim}
\anchor{<href>}{<text>}
\end{verbatim}
\end{quote}
\verb"<href>"\ should be specified as a \emph{full} URI, including the
\verb"scheme:"\ designator (|http:|, |ftp:|, etc.).
The \verb"\url" command supports the special case where an author
wishes to express a URL in the text.
\begin{quote}
\begin{verbatim}
\url{<text>}
\end{verbatim}
\end{quote}
The \verb"\email"\ command is used to identify e-mail addresses
anywhere in the manuscript.
The text of the argument is the e-mail address.
Please do \emph{not} prepend the \verb|mailto:| part.
\begin{quote}
\begin{verbatim}
\email{<address>}
\end{verbatim}
\end{quote}
This command should be used to indicate authors' e-mail addresses
in author lists at the beginning of manuscripts.
\subsection{Concluding the File}
The last command in the electronic manuscript file should be the
\begin{quote}
\begin{verbatim}
\end{document}
\end{verbatim}
\end{quote}
command, which must appear after all the material in the paper.
This command directs the formatter to finish processing the manuscript.
\section{Style Options} \label{styles}
\subsection{Manuscript Style}
The default style option is the |manuscript| style. This style will
produce double-spaced pages printed in a single column at the width
of the page.
\subsection{Preprints}
Two preprint styles are available.
The \texttt{preprint} style is similar to the |manuscript| style,
but it is single-spaced and fully justified.
The \texttt{preprint2} style produces a two-column preprint.
\subsubsection{Single-column Preprint}
A single-column preprint format may be specified with the
\texttt{preprint} style option.
\begin{quote}
\begin{verbatim}
\documentclass[preprint]{aastex}
\end{verbatim}
\end{quote}
The size of the typeface used is under author control by way of
\LaTeX's \m{nn}\texttt{pt} class options
(where \m{nn} is 10, 11, or 12).
Use of 10 point type is not recommended with the
\texttt{preprint} style.
\subsubsection{Two-column Preprint}
The
\texttt{preprint2} style
has the principle function of providing two-column formatting.
\begin{quote}
\begin{verbatim}
\documentclass[preprint2]{aastex}
\end{verbatim}
\end{quote}
It is important to remember
that text lines are considerably shorter when two columns are typeset
side by side on a page. Long equations, wide tables and figures, and
the like, may not typeset in this format without some adjustments.
The expenditure of great effort to adapt copy and markup for
two-column pages is counterproductive.
Remember that the main
goal of this package is to produce draft-, or referee-, format pages.
It is the responsibility of the editors and publishers to
produce publication-format papers for the journals.
The \texttt{preprint2} style
sets the article's front matter---the title, author, abstract,
and keyword material---on a separate page at full text width.
The body of the article is set in a two-column page grid,
the appendices in a one-column page grid,
and the bibliography in a two-column page grid.
(This manual was prepared using the \texttt{preprint2} style.)
The author may supply \LaTeX's \verb"\twocolumn"\ or |\onecolumn|
commands whenever desired.
Be aware, however, that using explicit column-switching commands can
cause formatting problems.
\subsection{The {\tt eqsecnum} Style}
The \texttt{eqsecnum} style file can be used to modify the way equations
are numbered.
\begin{quote}
\begin{verbatim}
\documentclass[eqsecnum]{aastex}
\end{verbatim}
\end{quote}
Normally, equations are numbered sequentially through the
entire paper, starting over at ``(A1)'' if there is an appendix.
If \texttt{eqsecnum} appears in the \texttt{documentclass} command,
equation num\-bers will be sequential through each section and will be
formatted ``({\it sec-eqn}),'' where ``{\it sec}'' is the current section number and
``{\it eqn}'' is the number of the equation within that section.
\subsection{The {\tt flushrt} Style }
A \verb"flushrt"\ style option is available for authors that prefer to
have their margins left and right justified.
\begin{quote}
\begin{verbatim}
\documentclass[eqsecnum,flushrt]{aastex}
\end{verbatim}
\end{quote}
Note the \texttt{preprint} and \texttt{preprint2} styles
are already flush right by default.
\section{Additional Documentation} \label{docs}
The preceding explanation of the markup commands in the
\aastex\ package has merit for defining syntax, but many
authors will prefer to examine the sample papers that are
included with the style files.
The files of interest are described below.
A comprehensive example employing nearly all of the capabilities
of the package (in terms of markup as well as formatting)
is in \verb"sample.tex".
This file is annotated with comments that describe
the purpose of most of the markup.
\verb"sample.tex"\ includes three tables: two marked up using the
\texttt{deluxetable} environment
and another table using the \LaTeX\ \texttt{table}
environment.
In \verb"table.tex", a complex but short example of the
\texttt{deluxetable} environment
demonstrates some of the techniques
that can be used to generate complex column headings and to align
variable-width columns.
Here the \LaTeX\ \verb"\multicolumn" command is used to span a heading
over several columns. When \verb"\multicolumn" is used along with the
\verb"\cutinhead" command, the \verb"\tablecolumns" command must be used to specify
the number of columns in the table---otherwise the \verb"\cutinhead" command
will not work properly.
This table also makes use of the \verb"\phn" command to better align some of the
columns.
This user guide (\verb"aasguide.tex")
is also marked up with the \aastex\ package,
although it is not exemplary as a scientific paper.
Many of the markup commands described in the preceding
sections are standard \LaTeX\ commands. The reader who is
unfamiliar with their syntax is referred to the \LaTeX\
references works cited in the bibliography, in particular
\citet{Kopka99} and \citet{Lamport}.
Authors who wish to know the ins and outs of \TeX\ itself
should read the \emph{\TeX book} \citep{Knuth}.
This resource contains a good deal of information about
typography in general. Many details of mathematical typography are
discussed in \emph{Mathematics into Type} by \citet{Swanson}.

%% This is a sample manuscript marked up using the
%% AASTeX v5.x LaTeX 2e macros.
%% The first piece of markup in an AASTeX v5.x document
%% is the \documentclass command. LaTeX will ignore
%% any data that comes before this command.
%% The command below calls the preprint style
%% which will produce a one-column, single-spaced document.
%% Examples of commands for other substyles follow. Use
%% whichever is most appropriate for your purposes.
%%
%%\documentclass[12pt,preprint]{aastex}
%% manuscript produces a one-column, double-spaced document:
\documentclass[manuscript]{aastex}
%% preprint2 produces a double-column, single-spaced document:
%% \documentclass[preprint2]{aastex}
%% Sometimes a paper's abstract is too long to fit on the
%% title page in preprint2 mode. When that is the case,
%% use the longabstract style option.
%% \documentclass[preprint2,longabstract]{aastex}
%% If you want to create your own macros, you can do so
%% using \newcommand. Your macros should appear before
%% the \begin{document} command.
%%
%% If you are submitting to a journal that translates manuscripts
%% into SGML, you need to follow certain guidelines when preparing
%% your macros. See the AASTeX v5.x Author Guide
%% for information.
\newcommand{\vdag}{(v)^\dagger}
\newcommand{\myemail}{skywalker@galaxy.far.far.away}
%% You can insert a short comment on the title page using the command below.
\slugcomment{Not to appear in Nonlearned J., 45.}
%% If you wish, you may supply running head information, although
%% this information may be modified by the editorial offices.
%% The left head contains a list of authors,
%% usually a maximum of three (otherwise use et al.). The right
%% head is a modified title of up to roughly 44 characters.
%% Running heads will not print in the manuscript style.
\shorttitle{Collapsed Cores in Globular Clusters}
\shortauthors{Djorgovski et al.}
%% This is the end of the preamble. Indicate the beginning of the

\begin{document}
%% LaTeX will automatically break titles if they run longer than

%% you desire.
\title{Collapsed Cores in Globular Clusters, \\
Gauge-Boson Couplings, and AAS\TeX\ Examples}
%% Use \author, \affil, and the \and command to format
%% author and affiliation information.
%% Note that \email has replaced the old \authoremail command
%% from AASTeX v4.0. You can use \email to mark an email address
%% anywhere in the paper, not just in the front matter.
%% As in the title, use \\ to force line breaks.

\section{Introduction}
A focal problem today in the dynamics of globular clusters is core collapse.
It has been predicted by theory for decades \citep{hen61,lyn68,spi85}, but
observation has been less alert to the phenomenon. For many years the
central brightness peak in M15 \citep{kin75,new78} seemed a unique anomaly.
Then \citet{aur82} suggested a central peak in \object{NGC 6397}, and a
limited photographic survey of ours \citep[Paper I]{djo84} found three more
cases, \objectname{NGC 6624}, \objectname[M 15]{NGC 7078}, and
\object[Cl 1938-341]{Terzan 8}), whose sharp center had often been
remarked on \citep{can78}.
\section{Observations}
%% In a manner similar to \objectname authors can provide links to dataset
%% hosted at participating data centers via the \dataset{} command. The
%% second curly bracket argument is printed in the text while the first
%% parentheses argument serves as the valid data set identifier. Large
%% lists of data set are best provided in a table (see Table 3 for an example).
%% Valid data set identifiers should be obtained from the data center that
%% is currently hosting the data.
All our observations were short direct exposures with CCD's. We also have
a random {\it Chandra} data set \dataset{ADS/Sa.ASCA\#X/86008020} and a
neat \dataset[ADS/Sa.HST#Y0Q70101T]{HST FOS spectrum} that readers can access
via the links in the electronic edition. Unfortunately this has nothing
whatsoever to do with this research. At Lick Observatory we used a TI 500$\times$500
chip and a GEC 575$\times$385, on the 1-m Nickel reflector. The only
filter available at Lick was red. At CTIO we used a GEC 575$\times$385, with
$B, V,$ and $R$ filters, and an RCA 512$\times$320, with $U, B, V, R,$ and $I$
filters, on the 1.5-m reflector. In the CTIO observations we tried to
concentrate on the shortest practicable wavelengths; but faintness, reddening,
and poor short-wavelength sensitivity often kept us from observing in $U$ or
even in $B$. All four cameras had scales of the order of 0.4 arcsec/pixel, and
our field sizes were around 3 arcmin.
The CCD images are unfortunately not always suitable, for very poor
clusters or for clusters with large cores. Since the latter are easily
studied by other means, we augmented our own CCD profiles by collecting
from the literature a number of star-count profiles
\citep{kin68,pet76,har84,ort85}, as well as photoelectric profiles
\citep{kin66,kin75} and electronographic profiles \citep{kro84}.
In a few cases we judged normality by eye estimates on one of the Sky
Surveys.
%% In this section, we use the \subsection command to set off
%% a subsection. \footnote is used to insert a footnote to the text.
%% Observe the use of the LaTeX \label
%% command after the \subsection to give a symbolic KEY to the
%% subsection for cross-referencing in a \ref command.
%% You can use LaTeX's \ref and \label commands to keep track of
%% cross-references to sections, equations, tables, and figures.
%% That way, if you change the order of any elements, LaTeX will
%% automatically renumber them.
%% This section also includes several of the displayed math environments
%% mentioned in the Author Guide.
\section{Helicity Amplitudes}
It has been realized that helicity amplitudes provide a convenient means
for Feynman diagram\footnote{Footnotes can be inserted like this.}
evaluations. These amplitude-level techniques
are particularly convenient for calculations involving many Feynman
diagrams, where the usual trace techniques for the amplitude
squared becomes unwieldy. Our calculations use the helicity techniques
developed by other authors \cite[]{hag86}; we briefly summarize below.
\subsection{Formalism} \label{bozomath}
%% The equation environment wil produce a numbered display equation.
A tree-level amplitude in $e^+e^-$ collisions can be expressed in
terms of fermion strings of the form
\begin{equation}
\bar v(p_2,\sigma_2)P_{-\tau}\hat a_1\hat a_2\cdots
\hat a_nu(p_1,\sigma_1) ,
\end{equation}
where $p$ and $\sigma$ label the initial $e^{\pm}$ four-momenta
and helicities $(\sigma = \pm 1)$, $\hat a_i=a^\mu_i\gamma_\nu$
and $P_\tau=\frac{1}{2}(1+\tau\gamma_5)$ is a chirality projection
operator $(\tau = \pm1)$. The $a^\mu_i$ may be formed from particle
four-momenta, gauge-boson polarization vectors or fermion strings with
an uncontracted Lorentz index associated with final-state fermions.
%% The \notetoeditor{TEXT} command allows the author to communicate
%% information to the copy editor. This information will appear as a
%% footnote on the printed copy for the manuscript style file. Nothing will
%% appear on the printed copy if the preprint or
%% preprint2 style files are used.
%% The eqnarray environment produces multi-line display math. The end of
%% each line is marked with a \\. Lines will be numbered unless the \\
%% is preceded by a \nonumber command.
%% Alignment points are marked by ampersands (&). There should be two
%% ampersands (&) per line.
In the chiral \notetoeditor{Figures 1 and 2 should appear side-by-side in
print} representation the $\gamma$ matrices are expressed
in terms of $2\times 2$ Pauli matrices $\sigma$ and the unit matrix 1 as
\begin{eqnarray}
\gamma^\mu & = &
\left(
\begin{array}{cc}
0 & \sigma^\mu_+ \\
\sigma^\mu_- & 0
\end{array} \right) ,
\gamma^5= \left(
\begin{array}{cc}
-1 & 0\\
0 & 1
\end{array} \right) , \nonumber \\
\sigma^\mu_{\pm} & = & ({\bf 1} ,\pm \sigma) , \nonumber
\end{eqnarray}
giving
\begin{equation}
\hat a= \left(
\begin{array}{cc}
0 & (\hat a)_+\\
(\hat a)_- & 0
\end{array}\right), (\hat a)_\pm=a_\mu\sigma^\mu_\pm ,
\end{equation}
The spinors are expressed in terms of two-component Weyl spinors as
\begin{equation}
u=\left(
\begin{array}{c}
(u)_-\\
(u)_+
\end{array}\right), v={\bf (}\vdag_+{\bf ,} \vdag_-{\bf )} .
\end{equation}
%% Putting eqnarrays or equations inside the mathletters environment groups
%% the enclosed equations by letter. For instance, the eqnarray below, instead
%% of being numbered, say, (4) and (5), would be numbered (4a) and (4b).
%% LaTeX the paper and look at the output to see the results.
The Weyl spinors are given in terms of helicity eigenstates
$\chi_\lambda(p)$ with $\lambda=\pm1$ by
\begin{mathletters}
\begin{eqnarray}
u(p,\lambda)_\pm & = & (E\pm\lambda|{\bf p}|)^{1/2}\chi_\lambda(p) , \\
v(p,\lambda)_\pm & = & \pm\lambda(E\mp\lambda|{\bf p}|)^{1/2}\chi
_{-\lambda}(p)
\end{eqnarray}
\end{mathletters}
%% This section contains more display math examples, including unnumbered
%% equations (displaymath environment). The last paragraph includes some
%% examples of in-line math featuring a couple of the AASTeX symbol macros.
\section{Floating material and so forth}
%% The displaymath environment will produce the same sort of equation as
%% the equation environment, except that the equation will not be numbered
%% by LaTeX.
Consider a task that computes profile parameters for a modified
Lorentzian of the form
\begin{equation}
I = \frac{1}{1 + d_{1}^{P (1 + d_{2} )}}
\end{equation}
where
\begin{displaymath}
d_{1} = \sqrt{ \left( \begin{array}{c} \frac{x_{1}}{R_{maj}}
\end{array} \right) ^{2} +
\left( \begin{array}{c} \frac{y_{1}}{R_{min}} \end{array} \right) ^{2} }
\end{displaymath}
\begin{displaymath}
d_{2} = \sqrt{ \left( \begin{array}{c} \frac{x_{1}}{P R_{maj}}
\end{array} \right) ^{2} +
\left( \begin{array}{c} \case{y_{1}}{P R_{min}} \end{array} \right) ^{2} }
\end{displaymath}
\begin{displaymath}
x_{1} = (x - x_{0}) \cos \Theta + (y - y_{0}) \sin \Theta
\end{displaymath}
\begin{displaymath}
y_{1} = -(x - x_{0}) \sin \Theta + (y - y_{0}) \cos \Theta
\end{displaymath}
In these expressions $x_{0}$,$y_{0}$ is the star center, and $\Theta$ is the
angle with the $x$ axis. Results of this task are shown in table~\ref{tbl-1}.
It is not clear how these sorts of analyses may affect determination of
$M_{\sun}$, but the assumption is that the alternate results
should be less than 90\degr\ out of phase with previous values.
We have no observations of \ion{Ca}{2}.
Roughly \slantfrac{4}{5} of the electronically submitted abstracts
for AAS meetings are error-free.

\section{Appendix material}
Consider once again a task that computes profile parameters for a modified
Lorentzian of the form
\begin{equation}
I = \frac{1}{1 + d_{1}^{P (1 + d_{2} )}}
\end{equation}
where
\begin{mathletters}
\begin{displaymath}
d_{1} = \frac{3}{4} \sqrt{ \left( \begin{array}{c} \frac{x_{1}}{R_{maj}}
\end{array} \right) ^{2} +
\left( \begin{array}{c} \frac{y_{1}}{R_{min}} \end{array} \right) ^{2} }
\end{displaymath}
\begin{equation}
d_{2} = \case{3}{4} \sqrt{ \left( \begin{array}{c} \frac{x_{1}}{P R_{maj}}
\end{array} \right) ^{2} +
\left( \begin{array}{c} \case{y_{1}}{P R_{min}} \end{array} \right) ^{2} }
\end{equation}
\begin{eqnarray}
x_{1} & = & (x - x_{0}) \cos \Theta + (y - y_{0}) \sin \Theta \\
y_{1} & = & -(x - x_{0}) \sin \Theta + (y - y_{0}) \cos \Theta
\end{eqnarray}
\end{mathletters}
For completeness, here is one last equation.
\begin{equation}
e = mc^2

%%
%% Begining of file `table.tex'
%% This complex but short example prepared in the deluxetable environment
%% demonstrates some of the techniques
%% that can be used to generate complex column headings and to align
%% variable-width columns. See the manuscript sample file, sample.tex,
%% for more table examples.
%% Note this file has its own \documentclass, \begin{document}, and
%% \end{document} commands. If you want to insert this table in another
%% LaTeX document using the \input command, comment out these lines.
\documentclass{aastex}
\begin{document}
%% Note that the table will print double-spaced since we are using the
%% manuscript style. Change the style to preprint or preprint2 to see
%% how LaTeX formats the table in those styles.
%% In this example the LaTeX \multicolumn command is used to span a heading
%% over several columns. When \multicolumn is used along with the
%% \cutinhead or \sidehead commands, the \tablecolumns command must
%% be used to specify the number of columns in the table -
%% otherwise \cutinhead and \sidehead will not work properly.
%% \cline has been used to produce straddle rules below the spanning heads,
%% \cutinhead to produce a centered head in the body of the table, and
%% \sidehead to produce a flush-left head in the body.
%% This table also makes use of the \phn command to better align some of the
%% columns. Also see \phd, \phs, and \phm{} - other commands useful for
%% column alignment. All of these commands insert a blank space
%% whose width is equal to that of a number (\phn),
%% a decimal point (\phd), a minus sign (\phs), or any
%% character you wish to use (\phm{text}).
%% Keep in mind that if you are preparing a table for electronic submission
%% to one of the journals, you need not worry too much about column
%% alignment. The editors will fix table alignment as appropriate.
%% If a table is more than one page long, the width of the table can vary
%% from page to page when the default \tablewidth is used, as below. The
%% individual table widths for each page will be written to the log file; a
%% maximum tablewidth for the table can be computed from these values.
%% The \tablewidth argument can then be reset and the file reprocessed, so
%% that the table is uniform throughout the pages. Try getting the widths
%% from the log file and changing the \tablewidth parameter to see how
%% adjusting this value affects table formatting.
%% The * option to the \\ command has been used in the lines after
%% the \sidehead to keep them together on the same page. Try taking
%% the *'s out and LaTeXing the manuscript again to see the difference
%% in the page breaks. You can group together as many lines as
%% you like using this command.
