\section{Introduction}
In order to ensure that papers received for publication from different
authors are consistent in format, style, and quality, authors are required
to type their manuscripts according to the following instructions.
The editors will modify the electronic manuscripts if necessary to ensure
that they conform to these standards.

\section{\LaTeX\ markup commands}
Authors using \LaTeX\ are requested to use the \verb"an" document 
class. It was derived from the \verb+article.cls+  class 
based on \TeX\ version 3.14159 and \LaTeXe. Hence formulae
and text are typed using the standard \LaTeX\ commands.

A copy of the style file, the \LaTeX\ source of this template file as well as
its PostScript-version are available via the web-pages of the editorial 
office of AN at the Astrophysical Institute Potsdam
(www.aip.de/AN) or on request via 
e-mail from the editor ({\it AN@aip.de}).

\subsection{Preamble}
The first piece of markup in the manuscript must declare the class of the 
document.
\begin{quote}
\verb"\documentclass{an}"
\end{quote}
The \verb"\documentclass" command must appear first in any \LaTeX\ file, and 
this one specifies the main style to be the {\tt an} style which uses 
ten point fonts. The font used by AN will be the \verb+times+
font. It is defined by the \verb+\usepackage{times}+ command following the 
\verb+\documentclass+ command. If the corresponding 
font-package is not available to authors, paper submission is also 
possible using the roman font, which is not too different from the 
times font as far as page layout etc.~is concerned.

\medskip
Next the author must include a statement about the page layout like 
\begin{quote}
\verb"\pagestyle{fancy}"\\
\end{quote}

The body of the text is embraced by the usual
\begin{quote}
\verb"\begin{document}"\\
{\it body of text}\\
\verb"\end{document}"
\end{quote}
commands which identify the beginning and end of the main portion of 
the manuscript.

\subsection{Layout of the heading section (Title, Author(s), Abstract, etc.)}
The  following  sequence of \LaTeX\ commands defines completely 
the heading section of the paper
\begin{quote}
\verb"\lhead[\thepage]{Author: Title}"\\
\verb"\rhead[Astron. Nachr./AN~{\bf XXX}\"
\verb+                (200X) X]{\thepage}+\\
\verb"\headnote{Astron. Nachr./AN {\bf XXX}"\\
\verb+                (200X) X, XXX--XXX}+\
\verb"\title{"{\it The title}\verb+}+\\
\verb"\author{"{\it A.N. Author}\\
\verb"\institute{"{\it The Author's Institute}\verb+}}+\\
\verb"\date{Received; accepted}"\\
\verb"\abstract{"\\
{\it Text of abstract}\\
\verb"\keywords{"\\
{\it list of keywords}\\
\verb"}"\\
\verb"\correspondence{"{\it current address or e-mail}\verb+}+\\
\verb"\maketitle"\\
\end{quote}
The frist three commands (\verb+\lhead, \lrhead, \headnote+)
can be omitted for submission of a paper, 
using them however, makes the paper looking close to the print version.
Title and author identification are generated with the standard \LaTeX\ 
commands \verb"\title" and \verb"\author". The authors name will be type-set
using the \verb+\sc+ ({\sc Small Caps}) font. 
In a separate line the author's affiliation is given using the 
\verb+\institute+ command. Some of the 
authors have alternate affiliations. Both affiliations can be defined in the 
\verb+\institute+ command separated by an \verb+\and+ command.
In addition, the use of the \verb+\footnote+ command is possible 
in order to acknowledge use of an observatory or similar. 

Should the paper have more than one author, include the co-author(s) 
name(s) in the \verb+\author+ and \verb+\institute+ commands. Use
the \verb+\and+ command as separator.
The present address or the current e-mail address of the corresponding 
author (either one from the list of authors) are defined via the the 
\verb+\correspondence+ command.

Next the abstract of your paper shall be given. 
Abstracts are required for all papers. 
Your abstract must be given using the 
\verb+\abstract+ command. Empty lines are not allowed within 
the summary. If you wish to break lines, 
use double backslashes \verb+\\+ instead.

A total of up to five keywords characterizing the main topics 
of the paper can be specified. These shall be selected from the list
of keywords which is accessible
via the WWW-page of AN. Keywords are part of the abstract 
and defined using the \verb+\keywords+ command.

The heading section is closed 
with the \verb+\maketitle+ command.

\subsection{Sectioning}
The {\tt an} style supports three levels of sectioning,
sections, subsections and subsubsections. 
If you wish to  open a new chapter, type 
\verb+\section{+{\it title of section}\verb+}+.
The \verb+\subsection+ and \verb+\subsubsection+ commands  
open subsections of different levels. These 
commands delimit sections by marking the {\it beginning} of each section;
there are no separate commands to identify the {\it ends}.

There is no capitalization in the titles of sections and subsections
except for proper names.

If one wishes to have an acknowledgements section, the \verb+\acknowledgements+
command will do. The text of the acknowledgement shall be typed thereafter. 
There is no separate command to identify the end of the acknowledgements.

Appendices can be defined using the \verb+appendix+ environment. Individual 
parts of an appendix can be separated with the \verb+\section+ command. They
will be numbered with capital letters \verb+A, B, C+ \dots.

\subsection{Figures}
Authors are welcome to include their figures and graphics as 
PostScript-files using the {\tt graphicx} package.
The name of the corresponding package
must be defined immediately following the \verb+\documentclass+ command
using e.g.~\verb+\usepackage{graphicx}+.

The standard width of a figure in AN is equal to the width of one 
column. The figure caption is set below the figure. 
Please note, that the height
of characters and digits in the finally printed manuscript must not be 
smaller than 2\,mm. The 
standard way for inclusion of a PostScript file then looks like this:
\begin{quote} 
\verb+\begin{figure}+\\
\verb+\resizebox{\hsize}{!}+\\
\verb+{\includegraphics[option]{+{\it file.eps}\verb+}}+\\
\verb+\caption{Caption text . . .}+\\
\verb+\label{label_for_figure}+\\
\verb+\end{figure}+\\
\end{quote}
where {\it file.eps} 
is the name of the file to be included. A number of options
defined in square brackets
help to correctly position and size your figure. These include 
parameters specifying e.g.~the {\tt height}, the {\tt width}, the {\tt angle}
or the BoundingBox {\tt bb}. For all the details of  
package authors are referred to the full description provided 
by the Comprehensive TeX Archive Network (CTAN) as {\tt epslatex.ps}
which can \hfill be \hfill retrieved \hfill 
from \hfill the \newline 
{\tt ftp://ftp.dante.de/tex-archive/info/} directory or one
of its mirrors.

\begin{figure}
\resizebox{\hsize}{!}
{\includegraphics[bbllx=70pt,bblly=303pt,bburx=522pt,bbury=755pt]{sombrero.eps}}
\caption{The caption of a figure shall describe the content of the figure.
An exception is granted only to the Editor and its ghostwriter, who
demonstrate the usage of this command.}
\label{label1}
\end{figure}

A large figure encompassing both columns shall be embraced 
by the \verb+\begin{figure*}+ and \verb+\end{figure*}+ commands.

If you cannot provide your figure as encapsulated PostScript file 
(but have glossy prints or photos instead), 
leave appropriate space at the desired location in the
text using the \verb+\vspace+ command in the  {\tt figure} environment.
Place your \verb+\caption+ as shown in the above example inside the 
environment.

Reproduction of color images on paper carries an extra charge. 
Costs are subject to 
changes and depend on how much color art is present in a particular issue;
an estimate will be given upon request. It should be noted that a certain 
level of color shift during the reproduction process 
will have to be accepted by the author. There is no limit for 
publication of color images in the electronic version of the paper
via Wiley Interscience (www.interscience.wiley.com). 
We encourage the authors to make intensive use of this feature.

\subsection{Movies}
As a novel feature AN offers the opportunity to publish movies 
in a refereed journal. Publication of the movies happens together with
the electronic version of the paper via Wiley Interscience 
(www.interscience.wiley.com). Submission of the movie requires 
upload to the Web-pages of AN (see www.aip.de/AN for further 
instructions). The movies will be reviewed by our referees. 

\subsection{Tables}
All tables shall be typeset with horizontal rules only. Vertical rules
shall be used only in exceptional cases for the sake of clarity. Tables should 
be accompanied by preceding captions. Secondary information 
can be given as a footnote to the table. Column headings label the 
entries in the column and should consist of one or two words, with the first
letter of each word capitalized. Units of table entries should be placed in 
parentheses immediately below the column headings. It is strongly suggested
to assign \LaTeX-labels to the table and to refer to individual tables in the 
text using the \verb+\ref{label_for_table}+ 
command in order not to lose the correct 
numbering if changes of the text occur. Table~\ref{tlab} shows an example.

\begin{table}[h]
\caption{Example of a well organized table}
\label{tlab}
%\begin{center}
\begin{tabular}{cc}\hline
Quantity 1 & Quantity 2\\ 
(unit1) & (unit2) \\
\hline
1 & 2 \\
3 & 4\\
\hline
\end{tabular}
%\end{center}
\end{table}

\subsection{Mathematics}
Formulae shall preferentially typeset using the \verb+equation+ 
environment, which guarantees automatic numbering of the formulae.
The use of the \verb+\ref - \label+-scheme within the 
environment  is strongly recommended. 
Punctuate a displayed equation in the same way as ordinary text.
Extensive mathematical calculations shall be put into an appendix
(see below).

In math mode \LaTeX{} treats all letters as though they were
mathematical or physical variables; hence they are typeset in italics.
However, any textual elements within formulae should be set in roman
by using the \\ \verb+\mathrm+ \verb+{text in roman}+ feature.
Roman should also be used for subscripts and superscripts \emph{in
formulae} where these are merely labels and not in themselves variables,
e.g.~\verb+$T_\mathrm{eff}+ \verb+= 5\,10^{9}$\,K+ produces
$T_\mathrm{eff} = 5\,10^{9}$\,K.
However, do not use roman if the subscripts or superscripts represent
variables, e.g.\ $\sum_{i=1}^{n} a_{i}$.

Please ensure that \emph{physical units} (e.g.\ pc, erg s$^{-1}$ K,
cm$^{-3}$, W m$^{-2}$ Hz$^{-1}$, m kg s$^{-2}$ A$^{-2}$) and {\em
abbreviations} such as Ord, Var, GL, SL, sgn, const.\ are always set in
roman type with an appropriate inter-word spacing. 
The names of common mathe\-matical functions, such as log,
sin, exp, max and sup shall be coded as \verb|\log|,
\verb|\sin|, \verb|\exp|, \verb|\max|, \verb|\sup| and will then
automatically appear in roman.

In order to distinguish ``d'' used as the ``differential sign'' and
``e'' used as the ``exponential function'' from normal variables, set
these letters in roman if used in this context.

Chemical symbols and formulae should be set in roman, e.g.\ Fe not $Fe$,
H$_{2}$O not {\em H$_{2}$O\/}, H$\alpha$ not {\em H${\alpha}$}.

\subsection{References}
The system to be followed for literature citations in the text 
is the standard one of the main 
astronomical journals. Hence, 
references should be cited by giving the last name of the
author and the date of publication, e.g., (Author 2001). 
Note that there is no
comma before the date. Papers by two authors should be cited by giving the
last names of both authors, joined by an ampersand, and the date, e.g.,
(Author1 \& Author2 2001). Again there is no comma before the date.
Papers by three authors should be cited by giving
the last names of all three authors on the first citation and the name of
the first author followed by et al.~thereafter, e.g., (Author1, Author2 \&
Author3 2001) at the first citation and (Author1 et al.~2001) in subsequent
citations. Papers by more than three authors should always be cited 
by giving the last name of the first author followed by et al.~and the year
of publication (Author1 et al.~2001).

Text references are placed in parentheses unless the author's name is
part of the sentence, e.g., (Author et al.~2001) but {\it 
as Author1 et al.~(2001) have shown}. 
If two or more papers are cited within a single set of
parentheses, the citations should be separated by a semicolon: 
(Author1 \& Author2 2001; Author3 1997).
If two or more papers by the same author(s) are
cited within a single set of parentheses, the dates of the papers should be
separated by a comma: (Author1 1997, 2001). Papers by the same author(s)
published in the same year should be distinguished by appending a, b, c,
etc., to the date: e.g., AnAuthor (1997a, 1997b). Parentheses are
omitted around the date if the reference appears in a table or in a note to
a table.

All sources cited in the text (including work in progress) must appear
in the reference section at the end of the paper and vice versa all entries 
in the reference section should be cited in the text. 
Reference entries should be
ordered alphabetically, starting with the last name of the first author,
followed by the first author's initial(s), and similarly for each additional
author. For papers with more than eight authors, the last name and initials
of the first three authors should be listed, 
with the names of subsequent authors
replaced by a comma and et al., but the paper should be alphabetically
positioned as it would be if the names of the all authors appeared. Multiple
entries for one author or one group of authors should be ordered
chronologically. There are commas between name(s) and initials, a colon before
and a comma 
after the year of publication, but no comma between the name of a journal
and the volume number. Journal names shall be abbreviated following 
the recommendations collected at 
http://adsdoc.harvard.edu/abs\_doc/refereed.html (e.g.~AN for Astronomische 
Nachrichten).

For creation of a reference list code as in the following example, 
for a sample output see below:
\begin{quote}
\verb+\begin{thebibliography}{}+\\
\verb+\bibitem{} Author1, A.B., +\\
\verb+     Author2, C.D.: 2001, AN~322, 1+\\
\verb+\bibitem{} Author3, E.F., +\\
\verb+     Author4, G.H.: 2001, AN~322, 10+\\
\verb+\end{thebibliography}+\\
\end{quote}

\section{General recommendations}
We recommend to pay attention to the following general hints
in order to avoid some common errors or inconsistencies:
\begin{itemize}
\item[--]
Acronyms and abbreviations should be spelled out the first time they
     are used unless they are common throughout the discipline. Terms
     defined in the abstract should be defined independently in the main
     text.
%\item[2]
%Chemical symbols should be in roman type, not italics. The mass number
%     precedes the symbol, e.g., $^\mathrm{12}$C.
\item[--]
Standard abbreviations for SI units (e.g., m, km, mm) or natural units
     (e.g., A.U., parsec, cm) should be used. If English units such as
     inches or pounds per square inch are used, metric equivalents should be
     given in parentheses.
\item[--]
Dates should be written in the order: year, month, and day; e.g., 2001
     January 1; the month being written in full, except in tables, where the
     standard three-letter abbreviations are used without a period.
\item[--]
In text, a sentence should not begin with a symbol or number.
\item[--] 
In a series of three or more items, a comma should be used to separate
     each item, and a comma is used before the last two items in the series,
     e.g., {\it space, time, and matter}.
\item[--]
The word {\it data} is plural and therefore takes a plural verb.
\end{itemize}
