\section{General}
\label{sec:intro}
Please use standard \LaTeX{} sectioning commands to subdivide your
document. You should use mixed case for the section titles, although
in the current style this only really matters at the level of
\CS{subsection} and below.
It is preferable to use the \CS{label}/\CS{ref}
mechanism\footnote{Note that this sometimes requires \LaTeX{} to be
run twice inorder to resolve all of the references.} for
cross-references in order to
\begin{inparaenum}[(1)]
\item minimise the chance of errors, and
\item allow automatic hyperlinks in PDF output (not yet implemented,
but will be soon).
\end{inparaenum}
The style that should be used for cross-references is, for example,
Figure~\ref{fig:crop}, Table~\ref{tab:ion_ab},
equation~(\ref{eq:one}), and \S~\ref{sec:EPS}, where the section
symbol ``\S'' is produced by the \LaTeX\ command ``\CS{S}''.
In \S~\ref{sec:errors}, I discuss a few pedantic points that I keep
running up against when editing papers. In \S~\ref{sec:EPS}, I discuss
some simple and not-so-simple ways of including postcript graphics. In
\S~\ref{sec:how-do-tables}, I discuss preparation of tables, focusing
on differences from standard \LaTeX{}. In \S~\ref{sec:refs}, I discuss
the style of citations and reference lists.
\section{Common Errors and How To Avoid Them}
\label{sec:errors}
Usually, the \emph{right} way of doing things is no more difficult
than the \emph{wrong} way.\footnote{Please let me know if you think
any of my advice in this section is wrong. I have made mistakes
before\dots} At least, this is true once you have had a bit of
practice \dots
\subsection{Special Commands Inherited from AAS Macros}
\label{sec:command}
The \texttt{rmaa} macros implement all the ``astronomical'' commands
defined in the AAS\TeX{} macros. Please try to use these since it
helps ensure consistency of appearance and usage between papers. In
many cases I have tried to improve on the AAS\TeX{}
implementations. Commonly used examples are
\begin{asparaitem}
\item The \CS{ion} command: \ion{H}{ii}, \ion{Fe}{26}, etc. This can
be happily used inside or outside math mode and inside figure
captions. The ion stage can be specified as an arabic or roman
numeral: \verb+\ion{H}{2}+, \verb+\ion{H}{ii}+, and
\verb+\ion{H}{II}+ will all produce the same output. One caveat:
\CS{ion} cannot be used inside the \CS{addkeyword} command---just
use \verb+H~II+ there if necessary.
\item The \CS{arcsec}, \CS{arcmin} and \CS{arcdeg} commands, together
with their ``fractional'' relatives, \CS{farcs}, etc. These are used
in the following way:
\begin{Example}
\dots at declination 15\arcdeg\,33\arcmin\,22\farcs{}2 \dots
\end{Example}
Again, they can be used inside or outside math mode.
\end{asparaitem}
\subsection{Math Symbols and Equations}
\label{sec:math}
Symbols for physical quantities should usually be italic: velocity,
$v$, density, $N$, etc. However, multi-letter symbols generally look
better in roman: FWHM, EM, etc. Subscripts should be in roman (coded
using \CS{mathrm}) unless they are themselves variables:
$N_\mathrm{e}$, $T_\mathrm{eff}$, but $\sum_i a_i$. Physical units
should in roman, with thin spaces: $10\,\mathrm{K}$, $1.2\times
10^{-12} \,\mathrm{erg\,cm^{-2}\,s^{-1}}$, etc. Things generally come
out best if you place an entire expression within a single pair of
\$'s and then make judicious use of \CS{mathrm}. For example
\begin{Example}
$ \mathrm{FWHM} = \int N_\mathrm{e} N_\mathrm{i} \, dz $
\end{Example}
Remember that the ``minus sign'' only exists inside math mode: minus
two is $-2$, not~-2, nor \hbox{even --2!} Also, remember that spacing inside
math mode is designed for equations, not words, so you shouldn't use
\$'s just to get italic text. Compare $effective$ and
\textit{effective}.
The \CS{frac} command (and its \TeX{} relative \CS{over}) are best
only used in displayed equations. Something like
\begin{equation}
\label{eq:one}
x = \frac { a + b } { c }
\end{equation}
looks fine, whereas $x = \frac { a + b } { c }$ is somewhat cramped.
Better rewritten as $x = (a + b) / c $.
\paragraph{How to define a macro that can be used inside or outside
math mode.} Use the \CS{ensuremath} command. For instance:
\begin{verbatim}
\newcommand{\fluxunits}{%
\ensuremath{\mathrm{%
erg\,s^{-1}\,cm^{-2}}}}
\end{verbatim}
Then you can write either \verb+15.1\,\fluxunits+ or
\verb+$2.3\times 10^{-11} \, \fluxunits$+
\subsection{Spacing After Periods}
\label{sec:space}
\TeX{}/\LaTeX{} distinguishes between inter-word spaces and
inter-sentence spaces. The latter are slightly wider and considerably
more ``stretchy'' than the former. A period that follows a lower-case
letter is assumed to end a sentence, while one that follows an
upper-case letter is not. This heuristic produces correct results
99\% of the time, but there are two cases where you need to give a
helping hand by using the \verb+\@+ command, which causes \LaTeX{} to
``forget'' what was just before it.
\paragraph{Lower case abbreviations ending in periods.} The only common
example is ``et~al.\@'', which should always be coded as, for example,
\begin{Example}
\verb+Henney et~al.\@ (2002).+
\end{Example}
Other examples, such as ``e.g.\@'' and ``i.e.\@'' should normally be
followed by a comma, so do not present this problem. The only other
example I have encountered is ``cf.\@'' but this should be followed by
a tie since we don't want a linebreak between it and the following
word:
\begin{Example}
\verb+(cf.~Jones 1990)+
\end{Example}
\paragraph{Sentences that end in a capital letter.} These are more common
than you might think and should be coded as in the following examples.
\begin{Example}
\verb+provided by NASA\@. Next sentence+\\
\makebox[1.05\width][s]{\dots provided by NASA\@. Next sentence \dots}\\[0.5\baselineskip]
\verb+a width of 1.5\,\AA\@. Next sentence+\\
\makebox[1.05\width][s]{\dots a width of 1.5\,\AA\@. Next sentence \dots}
\end{Example}
Note that ``\AA'' is considered by \LaTeX{} to be a capital letter, as
in the second example.
\subsection{Spacing in/after macros}
\label{sec:macrospace}
It is never a good idea to include explicit space at the end of a
definition of a user macro. Examples such as the following should be
avoided:
\begin{Example}
\verb+\newcommand{\kms}{km\,s$^{-1}$\ }+ \hfill\textbf{Wrong!}
\end{Example}
This will make the spacing come out right when you write
\begin{Example}
\newcommand{\kms}{km\,s$^{-1}$\ }
\verb+a speed of 5000~\kms is quite fast+\\
a speed of 5000\,\kms is quite fast
\end{Example}
but it won't work if the macro is followed by a punctuation mark, such
as
\begin{Example}
\newcommand{\kms}{km\,s$^{-1}$\ }
\verb+with values 5~\kms, 10~\kms, and+\\
with values 5\,\kms, 10\,\kms, and \dots
\end{Example}
The right way\footnote{Of course, an even better way would be to use
\CS{ensuremath}, as described above in \S~\ref{sec:math}} to go
about this is to define the macro without any following space:
\begin{Example}
\verb+\newcommand{\kms}{km\,s$^{-1}$}+ \hfill\textbf{Right!}
\end{Example}
Then, whenever you use the macro \emph{always} follow it with an empty
pair of braces, i.e., \verb+\kms{}+. That way the spacing will come
out right in all circumstances.
\subsection{Excessive Fiddling With the Layout }
\label{sec:fiddling}
The \texttt{rmaa} macros include various commands for final tweaking
of a paper, such as \CS{adjustfinalcols}, \CS{RescaleTitleLengths},
etc. In general you should leave all this to the editors. Yes, you may
have eliminated all the widows and orphans and beautifully balanced the
columns on the last page, but changing one word in the Spanish
abstract could well throw all that out of alignment\dots
\subsection{Other Little Things}
\label{sec:little}
By tradition, satellites should be in italic: \textit{HST},
\textit{ISO}, etc. Don't ask me why.
Compound adjectives are generally hyphenated, whereas the
corresponding noun is not. E.g., ``mass-loading rate'' but ``in the
absence of mass loading''. However, you shouldn't hyphenate a number
(written as digits) and a unit. E.g., ``using a 4~m telescope'', ``we
observed 15~GHz emission''.
A range of numbers is indicated by an ``en-dash'' (--), coded as
\verb+--+, as in ``in the range 4000--6000\,\AA''. An ``em dash''
(---), coded as \verb+---+ is used for punctuation. For example:
\begin{Example}
We also stress that our observations---at a single
wavelength---cannot confirm the thermal nature of the emission.
\end{Example}
There should be no space around the ``---''.
Numbers larger than 9999 should have a comma. E.g., 10,000\,K but
9000\,K\@.
\section{Including EPS Figures}
\label{sec:EPS}

\end{figure}
\begin{figure}[!t]\centering
\vspace{0pt}
\includegraphics[angle=-90,width=0.8\columnwidth]{example-fig}
\caption{Example of a rotated figure using the \texttt{angle}
keyword to \CS{includegraphics}. Note that in the general case of
a non-square figure, \texttt{angle=} should come before
\texttt{width=} to avoid confusion. In this example the figure has
also been reduced to 80\% of the column width and is centered by
means of the \CS{centering} command. You should not use the
\texttt{center} environment for this since it introduces unwanted
vertical space.}
\label{fig:rotate}
\end{figure}
\begin{figure}[!t]
\includegraphics[bb=8 13 135 35,clip,width=\columnwidth]{example-fig}
\caption{Example of a cropped figure using the \texttt{bb} and
\texttt{clip} keywords. The syntax is ``\texttt{bb =} $x_0$ $y_0$
$x_1$ $y_1$'' where $(x_0,y_0)$ and $(x_1,y_1)$ are the coordinates
(in points) of the bottom-left and upper-right corner,
respectively. Note that the EPS file used for this figure is the
same as in the other examples.}
\label{fig:crop}
\end{figure}
Figure~\ref{fig:simple} shows the simplest possible example of how to
include an EPS graphic file in a single-column figure. In order to
produce the highest-quality results and the smallest-possible EPS file
sizes, it is important to make sure you are using a vector format for
the text and line-art parts of the graphic. Failure to do so tends to
result in disasters like that shown in Figure~\ref{fig:bad}. Either
that, or, in an effort to produce acceptable quality lines and text
from a raster-format EPS file, you end up with the file being many
megabytes in size. A common cause of problems is the use programs such
as xv of ImageMagick. Once a postscript file has been read in by one
of these programs and then saved again (even if saved as postscript),
it has been irreversibly converted into a raster format, usually with
drastic concomitant loss of quality.
Sometimes your figure will come out sideways when you try to include
it. In this case you should use the \texttt{angle} keyword to
\CS{includegraphics}, as shown in Figure~\ref{fig:rotate}.
On other occasions, you only want to include a certain portion of the
EPS graphic. This can be achieved by means of the \texttt{bbox}
keyword, which allows you to manually specify the graphic's bounding
box, as illustrated in Figure~\ref{fig:crop}. You will also want to
use the \texttt{clip} keyword to prevent the unwanted parts of the
figure from being displayed. This technique is also useful in cases
where the bounding box specified in the EPS file is not ``tight''
around the graphic. The easiest way to find the bounding box you want
is to load the EPS file in gv or a similar program. Then, when you
move the mouse cursor over the figure, the coordinates (in points) of
the current cursor position should be shown in a little window at the
top-left. Thus, it is straightforward to find the coordinates of the
bottom-left and top-right corners of the desired rectangular region.
% Programs commonly used for generating postscript graphics do not
% generally make it easy to do complicated text formatting on the labels
% you put on the graph (e.g., greek letters, math equations).
% Thankfully, by means of the optional \texttt{psfrag} package, you can
% get \LaTeX{} to do this formatting for you. Put
% \CS{usepackage\{psfrag\}} in your preamble, then use commands of the
% form
% \CS{psfrag}\{\textsc{label}\}\discretionary{}{}{}\{\textsc{replacement}\}
% inside your \texttt{figure} environment but before the
% \CS{includegraphics} command, where \textsc{label} is the text in the
% EPS file and \textsc{replacement} is arbitrary \LaTeX{} mark-up that
% you wish to replace it with. An example is shown in
% Figure~\ref{fig:psfrag}. A minor disadvantage of this approach is that
% the results are only visible in the postscript output of dvips, not in
% the DVI file when viewed with xdvi.
% \begin{figure}[t!]

% \caption{Example of how to use the optional package \texttt{psfrag}

Figure~\ref{fig:widefig1} shows a double-column figure containing two
EPS graphics and Figure~\ref{fig:widefig2} is a more complicated
example of the same.

widths and spacing between them are set to be the same as that of
the columns of text (\CS{columnwidth} and \CS{columnsep})
respectively. Note the use of \texttt{\%} to suppress unwanted
spaces. Alternatively, you may want a single EPS graphic to span
the entire width, in which case you would put
\texttt{width=\CS{textwidth}} instead. In this example, both the
\texttt{width} and \texttt{height} keywords are used, forcing the
scaling to be anisotropic. You will never normally want to do
this.}

\label{fig:widefig2}
\end{figure*}
\paragraph{Color Graphics}
Color plates greatly increases the printing costs and so are best
avoided. On the other hand, including color figures in the online
version costs nothing. The best solution is for the author to provide
alternative grayscale versions of any color images, which can then be
used in the printed version. Otherwise, the way your beautiful color
picture gets converted to black-and-white will be entirely at the
mercy of the editors and printers. Remember, too, that grayscale
images generally look better on a negative scale.
\section{How To Do Tables}
\label{sec:how-do-tables}
An example of a simple table is given in Table~\ref{tab:ion_ab}. Some
points to note are:
\begin{asparaenum}
\item We use the \texttt{booktabs} package (loaded automatically),
which gives improved vertical layout with respect to the standard
\LaTeX{} version. As a user, the only impact of this is that you
must use \CS{toprule}, \CS{midrule}, and \CS{bottomrule} instead of
\CS{hline} to give the horizontal rules. Vertical rules should never
be used.
\item Footnotes to the table can be entered using a
\CS{tabnotemark}, \CS{tabnotetext} pair. Note that \CS{tabnotetext}
occurs inside the \texttt{tabular} environment and that for it to
work properly you must use the \CS{tablecols} command to specify the
number of columns in the table and set the length \CS{tabnotewidth}
to a sensible value.
\item The intercolumn spacing can be adjusted by setting the length
\CS{tabcolsep}. Things usually look best when this is set so that
the table fills the entire width of a text column as closely as
possible.
\item Missing data is indicated by the \CS{nodata} command, as in
AAS\TeX.
\end{asparaenum}
\begin{table}[!t]\centering

\end{table}
Table~\ref{tab:ioniz_av} is a somewhat more complicated example, this
time spanning both columns. Some features of this example are:
\begin{asparaenum}
\item The use of \CS{cmidrule} for partial horizontal rulres.
\item Somewhat elaborate adjustments to the horizontal spacing so as
to visually tie together subgroups of the columns. Two different
mechanisms are used to achieve this. That of putting in an empty
``ghost'' column is probably the easiest to manage. The other is to
use the \verb+@+ specifier with a user-defined horizontal space.

If your table will not fit on one page, you can use the \texttt{longtable}
package. I can provide an example of this on request.
\section{How To Do References}
\label{sec:refs}
The style of the reference list follows that of the ApJ, AJ, etc. That
is:
\begin{compactitem}
\item Comma after each surname, space between initials (unlike A\&A).
\item No comma before year.
\item Commas everywhere else.
\item If there are more then 6 authors you should use et~al.
\end{compactitem}
An almost bulletproof way of getting your reference list right is to
grab them from ADS (select ``AASTEX reference style''). The
\texttt{rmaa} macros recognize all the AAS journal abbreviation
commands.
In the text, references should be cited as follows:
\begin{Example}
\dots it has been found (Garc\'\i{}a 1990; L\'opez 2000a,b) that \dots
following Bloggs (1990) \dots is not true (despite what
Rodr\'\i{}guez 1759 maintains) \dots
\end{Example}
Note the use of semicolons between consecutive references and the lack
of comma between author and date. In order to save effort and reduce
errors, it is preferable to use commands from the \texttt{natbib}
package to automate the references in the text, as in the following
example:
\begin{Example}
\dots it has been found \citep{2005astro.ph.11035A,
1991ApJ...374..580B, 2005MNRAS.358..291D} that \dots following
\citet{1996ApJ...469..171G} \dots is not true (despite what
\citealp{1939ApJ....89..526S} maintains) \dots
\end{Example}
See \texttt{authorguide.pdf} for more examples and explanation. For
the reference keys, one can use the ADS bibliographic code, which is
the default for references obtained from ADS. Alternatively, if these
prove too hard to remember\footnote{There is no need to remember the
keys if you use an editor that understands \LaTeX{} references, such
as RefTeX mode in emacs.}, any mnemonic string may be used.
It is also possible to automate the generation of the reference list
itself using BibTeX, but support for this in the macros is still
experimental. For further details, see \texttt{authorguide.pdf}.
