From July 2021, all appendices are published as camera-ready material.

The success of the A&A journal brings with it a rapid growth in the number of articles and pages. As a consequence of this success and to keep down production costs, A&A will not typeset Appendices pages any longer but will include them at the end of the article as camera-ready material.

Appendices must be prepared even more carefully by the authors, because this part of the article will be published as camera-ready material, i.e., it will not be typeset by the Publisher. No correction, no copyediting, nor change of the layout in the appendices pages will be made in the LaTeX file after the receipt of the accepted version by the Publisher.

The following guide identifies the main layout issues we have identified, and how you can address them in the preparation of your Appendices in the LaTeX file:

Placement of the Appendices at the end of the article

Appendices are included at the end of the article, after the reference list (or after the long list of affiliations if any, in the PDF file): they must begin on the next page of the PDF file.

In the .tex file, put appendices after \end{thebibliography}.

After compilation with the new aa.cls file for the A&A class, appendices will be placed automatically on a new page.

Appendix sections

Put all the appendix sections into a single environment "appendix". Then all sections that follow will be numbered with capital letters. Please do NOT use the "\appendix" command instead of the environment "appendix", for a better management of the counters of Figure/Table which can be placed at the end of the article.

\section{Title of Appendix A}
\section{Title of Appendix B}

Labels and citations

Please use labels for each Figure/Table/Section/Reference, and for their citations, in the whole article, so that the hyperlinks will be functional in the final version (labels will not be added in the appendices, during the production).

Placement of illustrations (floats)

In the PDF file, each Figure/Table should be placed inside its own Appendix, not before the title of its Appendix, nor after the title of the next Appendix.

Reduction of the size of tables and figures can be applied for that, and also to avoid almost empty page before the illustration page.

In case you have a lot of floating objects for little text and LaTeX engine moves the floats away from their context, the command \FloatBarrier of the “placeins” package may allow you to empty the buffer of floats which are currently stored there, and therefore to place all the floats, already indicated before, in the continuity of the document.

Tables/figures longer than one page and/or wider than page width (landscape format)

For large tables or figures (longer than one page)

For large tables or figures (longer than one page) belonging to an appendix: the next parts of the illustration must keep the same numbering as the first part. The text of the caption on the next pages must be “continued.” (e.g.: “Table A.1. continued.” or “Fig. B.1. continued.”). Please, write “continued.” with the letter "c" in lower-case, not “Continued.”.

Please note that, for these long tables/figures, they will be placed automatically at the end of the document, after the whole appendices, in order to make compilation easier for the author. They will be moved inside the Appendices by the Publisher, if necessary.

% example for Table A.3:
\caption{Short caption of Table A.3.}\\
Def & mol & Ion & $\lambda$ & $\chi$ & $\log gf$ & N & e & rad & $\delta$ & $\delta$ red & References \\
Def & mol & Ion & $\lambda$ & $\chi$ & $\log gf$ & B & C & rad & $\delta$ & $\delta$ red & References \\
A & CH & 1 &3638 & 0.002 & $-$2.551 & & & & $-$150 & 150 & Jorgensen et al. (1996) \\
}% End longtab

For tables/figures longer than one page AND wider than page width (landscape format)

Additionally to the previous instructions:

  • in the preamble, use: \usepackage{lscape}, and add the command
  • and, in each concerned float, write:
% example for Table A.1:
}% End longtab
