+\keywords{Editorial notes -- instruction for authors}
+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
+( or on request via
+e-mail from the editor ({\it}).
+The first piece of markup in the manuscript must declare the class of the
+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.
+Next the author must include a statement about the page layout like
+The body of the text is embraced by the usual
+{\it body of text}\\
+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
+\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}"\\
+{\it Text of abstract}\\
+{\it list of keywords}\\
+\verb"\correspondence{"{\it current address or e-mail}\verb+}+\\
+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.
+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.
+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:
+\verb+{\includegraphics[option]{+{\it file.eps}\verb+}}+\\
+\verb+\caption{Caption text . . .}+\\
+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}
+which can \hfill be \hfill retrieved \hfill
+from \hfill the \newline
+{\tt} directory or one
+of its mirrors.
+\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.}
+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
+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 (
+We encourage the authors to make intensive use of this feature.
+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
+( Submission of the movie requires
+upload to the Web-pages of AN (see for further
+instructions). The movies will be reviewed by our referees.
+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.
+\caption{Example of a well organized table}
+Quantity 1 & Quantity 2\\
+(unit1) & (unit2) \\
+1 & 2 \\
+3 & 4\\
+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${\alpha}$}.
+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
+\_doc/refereed.html (e.g.~AN for Astronomische
+For creation of a reference list code as in the following example,
+for a sample output see below:
+\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+\\
+\section{General recommendations}
+We recommend to pay attention to the following general hints
+in order to avoid some common errors or inconsistencies:
+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.
+%Chemical symbols should be in roman type, not italics. The mass number
+%     precedes the symbol, e.g., $^\mathrm{12}$C.
+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.
+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.
+In text, a sentence should not begin with a symbol or number.
+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}.
+The word {\it data} is plural and therefore takes a plural verb.
+We appreciate the cooperation with the authors of AN.

+  Edinburgh, with funding from the UK Science and Engineering Research
