\section{Introduction}
\label{intro}

This article discusses several features of preparing preprints
with the \file{elsart} document style.  For more general
information about \LaTeX{}, see the \LaTeX{} manual written by
Lamport \cite{Lamp86} or the booklet \textit{Preparing Articles with
\LaTeX}, which is part of Elsevier Science's \LaTeX{} package (see below). 

All macro packages recommended in this document can be obtained from 
one of the servers of the Comprehensive TeX Archive Network (CTAN).
CTAN is a mirrored network of the FTP servers
\href{ftp://ftp.tex.ac.uk}{\texttt{ftp.tex.ac.uk}},
\href{ftp://ftp.dante.de}{\texttt{ftp.dante.de}} and
\href{ftp://ctan.tug.org}{\texttt{ctan.tug.org}}, which are widely mirrored (see
\url{ftp://ctan.tug.org/tex-archive/README.mirrors}) and hold
up-to-date copies of all the public-domain versions of \TeX, \LaTeX,
Metafont and ancillary programs.

Elsevier Science has prepared a \LaTeX{} package for authors,
which contains the following files:
\begin{itemize}
\item \file{ascii.tab} (ASCII table),
\item \file{elsart.cls} (use this file if you are using \LaTeXe, 
the current version of \LaTeX),
\item \file{elsart.sty} and \file{elsart12.sty}
(use these two files if you are using \LaTeX2.09, 
the now obsolete version of LaTeX),
\item \file{instraut.dvi} and/or \file{instraut.ps} (instruction booklet),
\item \file{readme}.
\end{itemize}
The package is freely available
from Elsevier Science's Web servers
  \begin{itemize}
    \item \url{http://www.elsevier.nl/locate/latex},
    \item \url{http://www.elsevier.com/locate/latex},
    \item \url{http://www.elsevier.co.jp/locate/latex},
  \end{itemize}
and from CTAN in the directory\newline
\href{ftp://ctan.tug.org/tex-archive/macros/latex/contrib/supported/elsevier}%
{\texttt{/tex-archive/macros/latex/contrib/supported/elsevier}}. 

\section{Abstract}

The abstract should be self-contained. Therefore, do not refer to the
list of references. Instead, quote the reference in full, as follows:
Wettig \& Brown (1996, NewA, 1, 17).

\section{Frontmatter}
\label{frontmatter}

The \texttt{elsart} document class has a separate 
\texttt{frontmatter} environment for the title, authors, addresses,
abstract and keywords.
\begin{itemize}
\item \verb|\title|: As in standard \LaTeX, e.g. 
\verb|\title{Model}|.
\item \verb|\author|: Different from standard \LaTeX, the \verb|\author|
command contains only one author and no address.
Multiple authors go into multiple \verb|\author| commands,
separated from each other by commas.
The address goes into a separate 
\verb|\address| command.
Example: \verb|\author{D.E. Knuth}|.
\item \verb|\address|: Here goes the address, e.g. 
\verb|\address{CERN, Geneva}|.
\item \verb|\thanks| and \verb|\thanksref|: 
These provide footnotes to the title, authors and addresses. 
The \verb|\thanks| command takes a label: \verb|\thanks[label]|
to relate it to the corresponding \verb|\thanksref| command, which 
has the same label: \verb|\thanksref{label}|. Example:
\verb|\title{Model\thanksref{titlefn}}| and
\verb|\thanks[titlefn]{Supported by grants.}|
\end{itemize}

It is not necessary to give a \verb|\maketitle| command. The title,
authors and addresses are printed as soon as \TeX{} sees them.

The authors and addresses can be combined in one of two ways:
\begin{itemize}
\item The simplest way lists the authors of one address, followed by
the address, and so on for all addresses.
\item The other way first lists all authors, and then all addresses.
The authors and addresses are related to each other by labels:
\verb|\author[label1]{Name1}| corresponds to
\verb|\address[label1]{Address1}|.
\begin{verbatim}
\author[South]{T.R. Marsh},
\author[Oxford]{S.R. Duck}
\address[South]{University of Southampton, UK}
\address[Oxford]{University of Oxford, UK}
\end{verbatim}
\end{itemize}

See the examples in figs.

\ref{ex:implinput}, \ref{ex:imploutput}.

FO Aqr is a member of the DQ~Her class of stars which
are close binary stars in which a magnetic white dwarf accretes from
a late-type main-sequence secondary star. These stars have most
recently been reviewed in Ref. [1].

\section{Keywords}
\label{keywd}

In electronic publications a proper classification is more important
than ever. Elsevier Science's physics journals use several keyword
schemes:\ 

\begin{description}
\item[Keywords:] Uncontrolled keywords.
\item[PACS:] The PACS scheme, developed and maintained by the AIP,
covers the whole field of Physics.
See \url{http://www.aip.org/pacs/pacs.html}
or \url{http://www.elsevier.nl/locate/pacs}.
\item[MSC:] The MSC scheme, developed and maintained by the AMS,
covers the whole field of Mathematics.
See \url{http://www.ams.org/msc}
or \url{http://www.elsevier.nl/locate/msc}.
\end{description}

Keywords are entered below the abstract in the following way:
\begin{verbatim}
\begin{keyword}
Keyword \sep Keyword
\PACS PACS code \sep PACS code
\MSC MSC code \sep MSC code
\end{keyword}
\end{verbatim}

\section{Cross-references}
\label{xrefs}

In electronic publications articles may be internally hyperlinked.
Hyperlinks are generated from proper cross-references in the article.

For example, the words Fig. 1 will never be more than simple text,
whereas the proper cross-reference \verb|\ref{mapfigure}| may be
turned into a hyperlink to the figure itself.

In the same way, the words Ref. [1] will fail to
turn into a hyperlink; the proper cross-reference is 
\verb|\cite{Gea97}|.

Cross-referencing is possible in \LaTeX{} for sections, subsections,
formulae, figures, tables, and literature references.

\section{PostScript figures}
\label{psfigs}

\LaTeX{} and PostScript have had a long and successful relationship.
In the current version of \LaTeX, \LaTeXe, there are three packages
for including PostScript figures:
\begin{itemize}
\item \texttt{graphics}.
This simple package provides the command\\
\verb|\includegraphics*[<llx,lly>][<urx,ury>]{file}|.
The \texttt{*} is optional; it enables the PostScript feature of clipping.
In its simplest form,\\
\verb|\includegraphics{file}|,
it includes the figure in the PostScript file \texttt{file}
without resizing.
\item \texttt{graphicx}.
This package provides the command\\
\verb|\includegraphics*[key--value list]{file}|.
The \texttt{*} is optional; it enables the PostScript feature of clipping.
Often used keys are:
\def\labelitemii{--}
\begin{itemize}
\item \texttt{scale=.40} to scale the size of the figure with 40\%,
\item \texttt{width=25pc}, \texttt{height=15pc} to set the width or
height of the figure,
\item \texttt{angle=90} to rotate the figure over $90^\circ$.
\end{itemize}
\item \texttt{epsfig}.
This package is really the \texttt{graphicx} package,
but it allows one to include PostScript figures using 
the familiar commands from 
the earlier packages \texttt{epsfig} and \texttt{psfig}.
\end{itemize}
For detailed information, see the documentation of the \texttt{graphics}
packages, in particular the file \texttt{grfguide.tex}.
\begin{figure}
\leftmargin=2pc
\begin{verbatim}
\begin{figure}
\begin{center}
\includegraphics*[width=5cm]{name.eps}
\end{center}
\caption{An example of a figure.}
\label{fig:exmp}
\end{figure}
\end{verbatim} 
\caption{An example of a figure.}
\label{fig:exmp}
\end{figure}

\section{Mathematical symbols}
\label{symbols}

Many physics authors require more mathematical symbols than the
few that are provided in standard \LaTeX. A useful package for
additional symbols is the \texttt{amssymb} package, developed by the American
Mathematical Society.  This package includes such oft used symbols as
\verb|\lesssim| for $\lesssim$, \verb|\gtrsim| for $\gtrsim$ or
\verb|\hbar| for $\hbar$.  Note that your \TeX{} system should have
the \texttt{msam} and \texttt{msbm} fonts installed.
If you need only a few symbols, such as \verb|\Box| for $\Box$,
you might try the package \texttt{latexsym}.

In the \texttt{elsart} document class vectors are preferably coded as 
\verb|\vec{a}| instead of \verb|\bf{a}| or \verb|\pol{a}|.

\section{The Bibliography}
\label{thebib}

In \LaTeX{} literature references are listed in the
\verb|thebibliography| environment. Each reference is a 
\verb|\bibitem|; each \verb|\bibitem| is identified by a label, by
which it can be cited in the text: \verb|\bibitem{ESG96}| is cited as
\verb|\cite{ESG96}|. In connection with cross-referencing and possible
future hyperlinking it is not a good idea to collect more that one
literature item in one \verb|\bibitem|.

\section{Template article}
\label{templart}

There is a template article \file{templat-num.tex}, which you can use as a
skeleton for your own article.
