\maketitle

\begin{abstract}
In this document, we provide a brief explanation about \texttt{pasj00.cls}, 
the current version of PASJ document class for authors.
Note that it is assumed that authors are used to writing documents in 
\LaTeX{} style; that is, this manual shows only the differences of 
functions provided by \texttt{pasj00.cls} and those in the \textit{standard} \LaTeX.  
Here, we use the phrase ``standard \LaTeX'' for ``\LaTeX{} without 
any optional package''. 
\end{abstract}

\section{Overview}
When \texttt{pasj00.cls} is applied to an article for PASJ, 
the article should be prepared in the standard \LaTeXe{} style with 
slight modifications.  
That is, a manu\-script has the following structure:
\begin{verbatim}
\documentclass{pasj00}

\begin{document}

\author{list of authors}
\affil{the authors' affiliation}
\title{title of the article}
%%% some other commands

\maketitle

\begin{abstract}
  abstract of the article
\end{abstract}

\section{First section}
%%% contents

\begin{thebibliography}{}%%% references
\bibitem[label]{key} reference entry
...
\end{thebibliography}
\end{document}
\end{verbatim}

The cross-reference system of \LaTeX{} is also available without restriction. 
If the \texttt{graphicx} package is available, figures in eps format can be 
embedded via the usual figure environment (see section~\ref{sec:figures}).

\textbf{Important Notice 1:}~The class file \texttt{pasj00.cls} is prepared 
so that the \textit{standard} \LaTeXe{} system is sufficient 
to typeset/preview articles for PASJ\@.  Therefore, this class uses 
the computer modern family for its default typeface, which is different 
from the current default typeface of the journal.  That is, authors can not 
obtain an identical image with the published article unless the class file
is not changed or replaced. 

\textbf{Important Notice 2:}~Though many parts of this document are also 
applicable to the file \texttt{pasj00.sty} which is the \LaTeX2.09 version of 
\texttt{pasj00.cls}, there are some differences based on those between 
\LaTeXe{} and \LaTeX2.09.  For example, graphic files can not be 
embedded in articles in the case of \texttt{pasj00.sty}. 
In the following, we refer to important differences between the two versions 
of \LaTeX, if necessary.


\section{Class options}
The document class file \texttt{pasj00.cls} admits the following options:
\begin{itemize}
\item \texttt{draft}: produce `overfull rules'
      (i.e.,~Black boxes will appear everywhere
       `overfull \verb/\hbox/' is occurred.)
\item \texttt{final}: hide `overfull rules'
\item \texttt{onecolumn}: use one-column format
\item \texttt{twocolumn}: use two-column format
\item \texttt{nofigure}: disable to embed eps figures
\item \texttt{proof}: typeset in draft-style for proofread
\item \texttt{useamsfonts}: enable to use symbols defined in \textsf{amssymb.sty}
\item \texttt{mfastrosym}: enable to use the font `astrosym'
\end{itemize}

Among these options, \texttt{nofigure} is most important.  
If there is no need to include eps figures in an article, 
or if the \texttt{graphicx} package is not available, 
one can quit loading the \texttt{graphicx} package by using 
the \texttt{nofigure} option.  Note that the \texttt{mfastrosym} option 
requires that the font `astrosym' (by Peter Schmitt) be \textit{properly} 
installed in the \TeX{} system. 


\section{Preamble commands}
To produce the title of an article, each article should contain the following 
five items:
\begin{enumerate}\raggedright
  \item a list of authors/their affiliation\\
        as~\verb/\author{/\textsl{authors}\verb/}/, 
             \verb/\affil{/\textsl{affiliation}\verb/}/
  \item title\\
        as~\verb/\title{/\textsl{title}\verb/}/
  \item date of reception/acception\\
        as~\verb/\Received{/\textsl{reception date}\verb/}/, 
           \verb/\Accepted{/\textsl{acception date}\verb/}/
  \item list of key words\\
        as~\verb/\KeyWords{/\textsl{key words}\verb/}/
  \item running head\\
        as \verb/\SetRunningHead{/\textsl{author(s) in page-head}\verb/}/\\
           \verb/{/\textsl{title in page-head}\verb/}/
\end{enumerate}

The e-mail address of each author is shown via \verb/\email/ command as:
\begin{quote}
  \verb/\email{/\textsl{e-mail address}\verb/}/
\end{quote}

The file \texttt{pasj.tex} is an example of usage of these commands. 

For a list of authors, it is commonly the case that one article has 
many groups of authors.  In such a case, \verb/\author/, \verb/\affil/ and 
\verb/\email/ can be used many times, as follows:
\begin{quote}
   \verb/\author{/%
      \textsl{FirstName${}_{11}$}%
      \verb/\textsc{/\textsl{FamilyName${}_{11}$}\verb/},/\\ \dots
      \textsl{FirstName${}_{1n_1}$}%
      \verb/\textsc{/\textsl{FamilyName${}_{1n_1}$}\verb/}/%
   \verb/}/ \\
   \verb/\affil{/\textsl{Affiliation${}_1$}\verb/}/\\
   \verb/\email{/\textsl{Address${}_{11}$}\verb/}/\\
   \dots\\
   \verb/\email{/\textsl{Address${}_{1n_1}$}\verb/}/\\
   \verb/\author{/%
      \textsl{FirstName${}_{21}$}%
      \verb/\textsc{/\textsl{FamilyName${}_{21}$}\verb/},/\\ \dots
      \textsl{FirstName${}_{2n_2}$}%
      \verb/\textsc{/\textsl{FamilyName${}_{2n_2}$}\verb/}/%
   \verb/}/ \\
   \verb/\affil{/\textsl{Affiliation${}_2$}\verb/}/\\
   \verb/\email{/\textsl{Address${}_{21}$}\verb/}/\\
   \dots\\
   \verb/\email{/\textsl{Address${}_{2n_2}$}\verb/}/\\
   \dots\\
   \verb/\and%%% separator of last two groups/\\
   \verb/\author{/%
      \textsl{FirstName${}_{m1}$}%
      \verb/\textsc{/\textsl{FamilyName${}_{m1}$}\verb/},/\\ \dots
      \textsl{FirstName${}_{mn_m}$}%
      \verb/\textsc{/\textsl{FamilyName${}_{mn_m}$}\verb/}/%
   \verb/}/ \\
   \verb/\affil{/\textsl{Affiliation${}_m$}\verb/}/\\
   \verb/\email{/\textsl{Address${}_{m1}$}\verb/}/\\
   \dots\\
   \verb/\email{/\textsl{Address${}_{mn_m}$}\verb/}/
\end{quote}

For example, the description
\begin{verbatim}
\author{Akio \textsc{Abe}
    and Ichiro \textsc{Tanaka}}
\affil{Some Institute\\ Somewhere}
\email{aabe@somelab.somewhere.ac.jp}
\email{itanaka@somelab.somewhere.ac.jp}
\and
\author{Daiki \textsc{Suzuki}}
\affil{Other Institute\\ Other place}
\email{dsuzuki@otherlab.otherplace.ac.jp}
\end{verbatim}
gives the following author list:
\begin{center}
  Akio \textsc{Abe} and Ichiro \textsc{Tanaka}\\
  {\small\textit{Some Institute\\ Somewhere}\\
  \textit{aabe@somelab.somewhere.ac.jp}\\
  \textit{itanaka@somelab.somewhere.ac.jp}}\\
  and\\
  Daiki \textsc{Suzuki}\\
  {\small\textit{Other Institute\\ Other place}\\
  \textit{dsuzuki@otherlab.otherplace.ac.jp}}
\end{center}

Though the \verb/\and/ command is used as a separator of the last two groups 
in this example, \verb/\and/ can be used to separate authors
in the argument of the \verb/\author/ command as in the standard \LaTeX.

If there is no one-to-one correspondence between the authors 
and the institutes, the author list might be written as in the example below:
\begin{verbatim}
\author{Author1,\altaffilmark{1}
        Author2,\altaffilmark{1,2}
        Author3,\altaffilmark{2}}
\altaffiltext{1}{Institute1}
\altaffiltext{2}{Institute2}
\end{verbatim}
This example gives the following list:
\begin{center}
  Author1,\altaffilmark{1} Author2,\altaffilmark{1,2} 
  Author3,\altaffilmark{2}\\
  {\small\textit{\altaffilmark{1}Institute1}\\
  \textit{\altaffilmark{2}Institute2}}
\end{center}

As shown in this example, the description 
\verb/\altaffilmark{/\textsl{label}\verb/}/ gives a label `\textsl{label}' 
and corresponding text is given by \verb/\altaffiltext/ with the same label 
`\textsl{label}' in its first argument. 


\section{Cross-references}
\subsection{\texttt{\textbackslash label}, \texttt{\textbackslash ref}, 
\texttt{\textbackslash cite} and thebibliography environment}
For cross-references of sections, figures, equations etc., the pair of 
commands \verb/\label/ and \verb/\ref/ is available.  Since the usage 
of these two commands is exactly the same as that in the standard \LaTeX, 
we leave the explanation about \verb/\label/ and \verb/\ref/ 
to adequate instructions of \LaTeX.

For citations, \texttt{pasj00.cls} provides the system of \verb/\cite/ and 
a `thebibliography' environment, as in the case of many other class files 
of \LaTeX.  The syntax of the `thebibliography' environment provided 
by \texttt{pasj00.cls} is as follows:
\begin{quote}
  \verb/\begin{thebibliography}{}/\\
  \verb/\bibitem[/\textsl{label}${}_1$\verb/]{/\textsl{key}${}_1$\verb/}/
  \textsl{entry}${}_1$\\
  \verb/\bibitem[/\textsl{label}${}_2$\verb/]{/\textsl{key}${}_2$\verb/}/
  \textsl{entry}${}_2$\\
  \dots\\
  \verb/\bibitem[/\textsl{label}${}_n$\verb/]{/\textsl{key}${}_n$\verb/}/
  \textsl{entry}${}_n$\\
  \verb/\end{thebibliography}/
\end{quote}
Note that \textsl{label}${}_1$, \dots, \textsl{label}${}_n$ do not appear
in the result of typesetting, but \verb/\cite{/\textsl{key}${}_1$\verb/}/ 
etc.\ consults those labels. 

\textbf{Important Notice:}~It is assumed that the optional argument 
of \verb/\bibitem/ (i.e.,~\textsl{label}${}_1$ etc.) is in the form 
``\textsl{author(s)}(\textsl{year of publication})'' 
as ``\texttt{A. Abe et al.(1997)}'', ``\texttt{A. Abe, I. Suzuki(1998)}'' 
or ``\texttt{D. Asuka(1999)}''.

\subsection{Miscellaneous citation commands}
In addition to the usual \verb/\cite/ command, \texttt{pasj00.cls} provides 
various citation commands.  In the following list, \textsl{key} is 
a reference key in the `thebibliography' environment and \textsl{author}, 
\textsl{year} are the corresponding authors and publication year, respectively. 
That is, the term 
\verb/\bibitem[/\textsl{author}\texttt{(}\textsl{year}\verb/)]{/%
\textsl{key}\verb/}/\dots{} is contained in the `thebibliography' environment. 
\begin{center}
\begin{tabular}{@{}ll@{}}
   \multicolumn{1}{c}{description}    &  \multicolumn{1}{c}{result}\\
   \verb/\cite{/\textsl{key}\verb/}/  & \textsl{author} \textsl{year}\\
   \verb/\citep{/\textsl{key}\verb/}/ & (\textsl{author} \textsl{year})\\
   \verb/\citet{/\textsl{key}\verb/}/ & \textsl{author} (\textsl{year})\\
   \verb/\authorcite{/\textsl{key}\verb/}/  & \textsl{author}\\
   \verb/\yearcite{/\textsl{key}\verb/}/    & \textsl{year}
\end{tabular}
\end{center}

If a comma-separated list of reference keys is given as an argument 
of the \verb/\cite/ command, we obtain a semicolon-separated list 
of reference labels.  For other commands, readers can easily find 
the result for a list of keys by simple experiments. 


\section{Mathematical formulas}
For mathematical formulas, the class \texttt{pasj00.cls} allows 
a \verb/$...$/ and `math' environment for in-text formulas, and 
\verb/\[...\]/, environments `displaymath', `equation' and
`eqnarray($*$)' for displayed formulas.  Since mathematical formulas 
are not aligned in the center, the use of \verb/$$...$$/ for 
a displayed formula is not recommended.  

For mathematical symbols, \textsf{pasj00.cls} allows one to use symbols 
provided by the standard \LaTeXe{} and some more symbols given 
in Table~\ref{table:extramath} (see also section \ref{sec:math-symbols}). 
Note that if the \texttt{amssymb} package is available, 
the \texttt{useamsfonts} class option enables the use of symbols defined 
by \textsf{amssymb.sty}. 


\section{Figures}\label{sec:figures}
The class file \texttt{pasj00.cls} supports the embeddings of graphic 
files in the \textit{eps} format as its default.  (Note that \texttt{pasj00.sty}
does not support graphic files.)  A graphic file \textsl{filename.eps} can 
be included by using the \verb/\FigureFile/ command, as follows:
\begin{quote}
  \verb/\FigureFile(/\textsl{width}\verb/,/\textsl{height}\verb/){/%
  \textsl{filename.eps}\verb/}/
\end{quote}
Here, \textsl{width} and \textsl{height} are the width of the figure 
in \textsl{filename.eps} and the height of the figure, respectively. 
For example, if a file \texttt{fig1.eps} contains a figure of width 70mm
and height 50mm, this figure is placed 
by \verb/\FigureFile(80mm,50mm){fig1.eps}/. 
(When the `BoundingBox' information is used for figure sizes, 
authors might remember that the unit `pt' in PostScript is the same 
as `bp' in \TeX.)

For the location of figure files (or the directory/folder in which 
figure files exist), \texttt{pasj00.cls} assumes that figure files and 
the \LaTeX{} file containing those figures are placed in the same directory. 
If figure files are placed in a different directory from that which contains 
the \LaTeX{} document, the relative path of the directory containing 
figures is specified by the \verb/\RelativeFigurePath/ command in the preamble
(of the \LaTeX{} docuemnt), as follows:
\begin{quote}
  \verb/\RelativeFigurePath/\\
  \verb/{/\textsl{relative path of figure-directory}\verb/}/
\end{quote}
Here, `relative path' is the relative path from the directory containing
the \LaTeX{} document with the \verb/\RelativeFigurePath/ command. 

For example, assume that a \LaTeX{} document, T, is placed in a directory, D,
and that figure files are in a subdirectory SUB of D; in this case
we can put ``\verb/\RelativeFigurePath{SUB}/'' in the preamble of document T, 
and each \verb/\FigureFile/ command has a filename (without path) 
and figure sizes, as its arguments.  Note that authors \textit{should not} 
include path information in the argument of the \verb/\FigureFile/ command, 
because path information forces the publisher/editors to construct
the same structure of directories as that of authors. 

Similar to the \verb/\includegraphics/ command, the \verb/\FigureFile/ 
command only includes a graphic file.  To place figures appropriately, 
the usual `figure' environment is available.  As in the standard \LaTeX, 
\texttt{pasj00.cls} allows the following description and
Figure~\ref{fig:usage} is an example of the `figure' environment.
\begin{verbatim}
\begin{figure}
  \begin{center}
    \FigureFile(80mm,50mm){fig.eps}
  \end{center}
  \caption{*****}\label{.....}
\end{figure}
\end{verbatim}
\begin{figure}
  \begin{center}
    \begin{picture}(200,100)
      \put(  5,  5){\line( 0, 1){ 90}}
      \put(  5,  5){\line( 1, 0){190}}
      \put(195,  5){\line( 0, 1){ 90}}
      \put(  5, 95){\line( 1, 0){190}}
      \put(  5,  5){\line( 2, 1){ 90}}
      \put(  5, 95){\line( 2,-1){ 90}}
      \put(195,  5){\line(-2, 1){ 90}}
      \put(195, 95){\line(-2,-1){ 90}}
      \put( 95, 50){\line( 1, 0){ 10}}
      \put(  5,  5){\circle {6}}
      \put(195,  5){\circle*{6}}
      \put(  5, 95){\circle*{6}}
      \put(195, 95){\circle {6}}
    \end{picture}
  \end{center}
  \caption{%
     Simple example of usage of the `figure' environment.
     This sample figure is a `picture' environment and no eps file 
     is included.  If the \texttt{graphicx} package is available 
     and some appropriate graphic files exist, readers might 
     observe the usage of the \texttt{\textbackslash FigureFile} command.}%
  \label{fig:usage}
\end{figure}

Though the `figure' environment can take one optinal argument showing 
possible positions of the figure, the use of this optional argument is 
not recommended.  

\textbf{Important Notice:}~Graphic files can be included \textit{only} via
the \verb/\FigureFile/ command.  Note that authors \textit{must not} use 
old packages for graphics, such as \texttt{epsf.sty}, \texttt{epsbox.sty}. 
Even for the \texttt{graphicx} package, the \verb/\includegraphics/ command 
can not be used directly.

\textsc{Remark for \LaTeX2.09:}~Since there is no \textit{standard} method 
to include graphic files in the case of \LaTeX2.09, \texttt{pasj00.sty} 
does not support the embeddings of graphic files.  But, the \verb/\FigureFile/ 
command is available, as in the case of \LaTeXe, and \verb/\FigureFile/ 
only produces a blank rectangle with a filename. 


\section{Tables}
To include tables which are small enough to be contained in one page, 
the usual pair of `table' and `tabular' environments is available.  
That is, authors can place a small table as in the following way:
\begin{verbatim}
\begin{table}
  \caption{***}\label{...}
  \begin{center}
    \begin{tabular}{lll}
      ..........
    \end{tabular}
  \end{center}
\end{table}
\end{verbatim}

To produce long tables, (a simplified version of) the `longtable' environment 
is implemeted.  The usege of the `longtable' environment is very similar to 
that of the `longtable' environment provided by the \texttt{longtable} package. 
Thus, a long table can be described as follows:
\begin{verbatim}
\begin{longtable}{*{8}{l}}
\caption{caption of this tabular}
\hline
\multicolumn{8}{c}{first head} \\
A & B & C & D & E & F & G & H  \\
\hline
\endfirsthead
\hline
A & B & C & D & E & F & G & H  \\
\hline
\endhead
\hline
\endfoot
\hline
\multicolumn{8}{l}{some remarks...} \\
\hline
\endlastfoot
a & b & c & d & e & f & g & h \\
............%%% table data
a' & b' & c' & d' & e' & f' & g' & h' \\
\end{longtable}
\end{verbatim}

Note that this `longtable' environment obtains the maximum size 
of the width of cells in each column via the aux file.  Therefore, it is 
required to typeset at least twice to produce a correct table.  
For the meanings of \verb/\endhead/ etc., see ``The \LaTeX{} Companion'' or 
appropriate instruction for \LaTeXe.

\textbf{Important Notice~1:}~Since this `longtable' environemnt, itself, 
is treated like table environments, there is no need to put a longtable 
in a table environment. 

\textbf{Important Notice~2:}~In the `longtable' environment, \verb/\caption/ 
should be placed at the first part of this environment.  
Though the \texttt{longtable} package provides some parameters, like 
\verb/\LTleft/ and \verb/\LTpre/, the \texttt{pasj00.cls} class file 
inhibits one to use those parameters in order to keep the uniformity of 
the appearance of the tables in the journal. 


\section{Miscellaneous remarks}
\subsection{Additional mathematical symbols}\label{sec:math-symbols}
The symbols in Table~\ref{table:extramath} are provided by \textsf{pasj00.cls}. 
Some of them are also defined in \textsf{amssymb.sty}, and 
the definitions of such commands are replaced with those 
in \textsf{amssymb.sty} if \texttt{useamsfont} option is specified.

\subsection{Description of time/angle, atoms etc.}
To produce the description of time/angle like ``\timeform{1h23m45.67s}''
or ``\timeform{6D54'32.1''}'', the class file \textsf{pasj00.cls} provides 
a simple notation \verb/\timeform{1h23m45.67s}/ or 
\verb/\timeform{6D54'32.1''}/.  In the argument of \verb/\timeform/ command, 
the letter `\texttt{D}' corresponds to the symbol `\degree'. 
Note that all of the three expressions \verb/\timeform{1.23s}/, 
\verb/\timeform{1s.23}/ and \verb/\timeform{1.s23}/ give the same result
``\timeform{1.23s}'', that is, there is no importance in the order of 
a decimal point and a unit symbol.  Also, we note that the \verb/\timeform/ 
command assumes that there is \textit{at most one} decimal point 
in its argument. (Though the class file \textsf{pasj00.cls} provides 
an abbreviation \verb/\TF/ of \verb/\timeform/, this abbreviation 
is not preferable.)

Though the file \textsf{pasj00.cls} also provides (\textsf{aastex}-like) 
commands, such as \verb/\fh/(\fh), \verb/\fdg/(\fdg), 
the use of such commands with ambiguous names is not recommended. 

Atomic symbols like ``\atom{C}{}{12}'' or ``\atom{N}{7}{14}'' can be produced 
by ``\verb/\atom{C}{}{12}/'' or ``\verb/\atom{N}{7}{14}/'' respectively.

\subsection{Draft mode}
The class file \texttt{pasj00.cls} provides the \verb/\draft/ command 
to produce a one-column, double-spaced document with 12pt fonts. 
The \verb/\draft/ command could be simply placed in the preamble 
of an article. 


\subsection{About user-defined commands}
Though class file \textsf{pasj00.cls} does not inihibit the use 
of \verb/\def/, \verb/\newcommand/ etc., it is \textit{not} recommended 
to define a user's own command.  Note that a user's own trivial abbriviations 
might cause fatal errors by changing the existing commands or by interfering 
with macros defined in other articles (or in the class file used 
for publication).  Every author should remember that \textit{no} journal 
consists of his/hers papers only.
