+%%
+%% Revision 1.18 2019/6/3 Amy Hendrickson
+%% Took out `v' preceding version number in @misc
+%%
+%% Rewrote format.pid to implement this precedence:
+%% if doi, print that, if eprint print that, if neither
+%% and there is a url, use the url
+
+%% Took out format.url output generally because it is included in format.pid,
+%% so undesirable to call for it a second time.
+
+%%
+%% Revision 1.17 2019/3/15 Amy Hendrickson
+%% Added DOI to every field where format.url was found. Kept format.url in case
+%% it is needed.

+
+AASTEX was designed and written by Chris Biemesderfer in 1988. Substantial revisions were made by Lee Brotzman and Pierre Landau when the package was updated to v4.0. AASTEX was rewritten as a LATEX class by Arthur Ogawa for the v5.0 release. It was updated to v5.2 by SR Nova Private Ltd. Amy Hendrickson (TEXnology Inc.) wrote the v6.0 release which itself was primarily based on the emulateapj classfile created by Maxim Markevitch and Alexey Vikhlinin. Amy Hendrickson also created versions v6.1 - v6.3. Over the years the documentation has benefited from revisions by Jeannette Barnes, Sara Zimmerman, Greg Schwarz, Gus Meunch, Amy Henderickson, and Butler Burton.

-\begin{quote}\slshape
-For a more detailed description of the \thestyle\ package, \LaTeX\ the
-source file \thestyle\texttt{.dtx}.
-\end{quote}
-\head{Overview}
-The \thestyle\ package is a reimplementation of the \LaTeX\ |\cite| command,
-to work with both author--year and numerical citations. It is compatible with
-the standard bibliographic style files, such as \texttt{plain.bst}, as well as
-with those for \texttt{harvard}, \texttt{apalike}, \texttt{chicago},
-\texttt{astron}, \texttt{authordate}, and of course \thestyle.
-
-\head{Loading}
-Load with |\usepackage[|\emph{options}|]{|\thestyle|}|. See list of
-\emph{options} at the end.
-
-\head{Replacement bibliography styles}
-I provide three new \texttt{.bst} files to replace the standard \LaTeX\
-numerical ones:
-\begin{quote}\ttfamily
- plainnat.bst \qquad abbrvnat.bst \qquad unsrtnat.bst
-\end{quote}
-\head{Basic commands}
-The \thestyle\ package has two basic citation commands, |\citet| and
-|\citep| for \emph{textual} and \emph{parenthetical} citations, respectively.
-There also exist the starred versions |\citet*| and |\citep*| that print
-the full author list, and not just the abbreviated one.
-All of these may take one or two optional arguments to add some text before
-and after the citation.
-\begin{quote}
-\begin{tabular}{l@{\quad$\Rightarrow$\quad}l}
-  |\citet{jon90}| & Jones et al. (1990)\\
-  |\citet[chap.~2]{jon90}| & Jones et al. (1990, chap.~2)\\[0.5ex]
-  |\citep{jon90}| & (Jones et al., 1990)\\
-  |\citep[chap.~2]{jon90}| & (Jones et al., 1990, chap.~2)\\
-  |\citep[see][]{jon90}| & (see Jones et al., 1990)\\
-  |\citep[see][chap.~2]{jon90}| & (see Jones et al., 1990, chap.~2)\\[0.5ex]
-  |\citet*{jon90}| & Jones, Baker, and Williams (1990)\\
-  |\citep*{jon90}| & (Jones, Baker, and Williams, 1990)
-\end{tabular}
-\end{quote}
-\head{Multiple citations}
-Multiple citations may be made by including more than one
-citation key in the |\cite| command argument.
-\begin{quote}
-\begin{tabular}{l@{\quad$\Rightarrow$\quad}l}
-  |\citet{jon90,jam91}| & Jones et al. (1990); James et al. (1991)\\
-  |\citep{jon90,jam91}| & (Jones et al., 1990; James et al. 1991)\\
-  |\citep{jon90,jon91}| & (Jones et al., 1990, 1991)\\
-  |\citep{jon90a,jon90b}| & (Jones et al., 1990a,b)
-\end{tabular}
-\end{quote}
-
-\head{Numerical mode}
-These examples are for author--year citation mode. In numerical mode, the
-results are different.
-\begin{quote}
-\begin{tabular}{l@{\quad$\Rightarrow$\quad}l}
-  |\citet{jon90}| & Jones et al. [21]\\
-  |\citet[chap.~2]{jon90}| & Jones et al. [21, chap.~2]\\[0.5ex]
-  |\citep{jon90}| & [21]\\
-  |\citep[chap.~2]{jon90}| & [21, chap.~2]\\
-  |\citep[see][]{jon90}| & [see 21]\\
-  |\citep[see][chap.~2]{jon90}| & [see 21, chap.~2]\\[0.5ex]
-  |\citep{jon90a,jon90b}| & [21, 32]
-\end{tabular}
-\end{quote}
-\head{Suppressed parentheses}
-As an alternative form of citation, |\citealt| is the same as |\citet| but
-\emph{without parentheses}. Similarly, |\citealp| is |\citep| without
-parentheses. Multiple references, notes, and the starred variants
-also exist.
-\begin{quote}
-\begin{tabular}{l@{\quad$\Rightarrow$\quad}l}
-  |\citealt{jon90}| & Jones et al.\ 1990\\
-  |\citealt*{jon90}| & Jones, Baker, and Williams 1990\\
-  |\citealp{jon90}| & Jones et al., 1990\\
-  |\citealp*{jon90}| & Jones, Baker, and Williams, 1990\\
-  |\citealp{jon90,jam91}| & Jones et al., 1990; James et al., 1991\\
-  |\citealp[pg.~32]{jon90}| & Jones et al., 1990, pg.~32\\
-  |\citetext{priv.\ comm.}| & (priv.\ comm.)
-\end{tabular}
-\end{quote}
-The |\citetext| command
-allows arbitrary text to be placed in the current citation parentheses.
-This may be used in combination with |\citealp|.
-\head{Partial citations}
-In author--year schemes, it is sometimes desirable to be able to refer to
-the authors without the year, or vice versa. This is provided with the
-extra commands
-\begin{quote}
-\begin{tabular}{l@{\quad$\Rightarrow$\quad}l}
-  |\citeauthor{jon90}| & Jones et al.\\
-  |\citeauthor*{jon90}| & Jones, Baker, and Williams\\
-  |\citeyear{jon90}|   & 1990\\
-  |\citeyearpar{jon90}| & (1990)
-\end{tabular}
-\end{quote}
-\head{Forcing upper cased names}
-If the first author's name contains a \textsl{von} part, such as ``della
-Robbia'', then |\citet{dRob98}| produces ``della Robbia (1998)'', even at the
-beginning of a sentence. One can force the first letter to be in upper case
-with the command |\Citet| instead. Other upper case commands also exist.
-\begin{quote}
-\begin{tabular}{rl@{\quad$\Rightarrow$\quad}l}
-  when & |\citet{dRob98}| & della Robbia (1998) \\
-  then & |\Citet{dRob98}| & Della Robbia (1998) \\
-     &   |\Citep{dRob98}| & (Della Robbia, 1998) \\
-     &   |\Citealt{dRob98}| & Della Robbia 1998 \\
-     &   |\Citealp{dRob98}| & Della Robbia, 1998 \\
-     &   |\Citeauthor{dRob98}| & Della Robbia
-\end{tabular}
-\end{quote}
-These commands also exist in starred versions for full author names.
-
-\head{Citation aliasing}
-Sometimes one wants to refer to a reference with a special designation,
-rather than by the authors, i.e. as Paper~I, Paper~II. Such aliases can be
-defined and used, textual and/or parenthetical with:
-\begin{quote}
-\begin{tabular}{lcl}
-  |\defcitealias{jon90}{Paper~I}|\\
-  |\citetalias{jon90}| & $\Rightarrow$ & Paper~I\\
-  |\citepalias{jon90}| & $\Rightarrow$ & (Paper~I)
-\end{tabular}
-\end{quote}
-These citation commands function much like |\citet| and |\citep|: they may
-take multiple keys in the argument, may contain notes, and are marked as
-hyperlinks.
-\head{Selecting citation style and punctuation}
-Use the command |\bibpunct| with one optional and 6 mandatory arguments:
-\begin{enumerate}
-\item the opening bracket symbol, default = (
-\item the closing bracket symbol, default = )
-\item the punctuation between multiple citations, default = ;
-\item the letter `n' for numerical style, or `s' for numerical superscript
-      style, any other letter for
-      author--year, default = author--year;
-\item the punctuation that comes between the author names and the year
-\item the punctuation that comes between years or numbers when common author
-      lists are suppressed (default = ,);
-\end{enumerate}
-
-The optional argument is the character preceding a post-note, default is a
-comma plus space. In redefining this character, one must include a space if
-one is wanted.
-
-Example~1, |\bibpunct{[}{]}{,}{a}{}{;}| changes the output of
-\begin{quote}
-  |\citep{jon90,jon91,jam92}|
-\end{quote}
-into [Jones et al. 1990; 1991, James et al. 1992].
-
-Example~2, |\bibpunct[; ]{(}{)}{,}{a}{}{;}| changes the output of
-\begin{quote}
-  |\citep[and references therein]{jon90}|
-\end{quote}
-into (Jones et al. 1990; and references therein).
-
-\head{Other formatting options}
-Redefine |\bibsection| to the desired sectioning command for introducing
-the list of references. This is normally |\section*| or |\chapter*|.
-
-Define |\bibpreamble| to be any text that is to be printed after the heading but
-before the actual list of references.
-
-Define |\bibfont| to be a font declaration, e.g.\ |\small| to apply to
-the list of references.
-
-Define |\citenumfont| to be a font declaration or command like |\itshape|
-or |\textit|.
-
-Redefine |\bibnumfmt| as a command with an argument to format the numbers in
-the list of references. The default definition is |[#1]|.
-
-The indentation after the first line of each reference is given by
-|\bibhang|; change this with the |\setlength| command.
-
-The vertical spacing between references is set by |\bibsep|; change this with
-the |\setlength| command.
-
-\head{Automatic indexing of citations}
-If one wishes to have the citations entered in the \texttt{.idx} indexing
-file, it is only necessary to issue |\citeindextrue| at any point in the
-document. All following |\cite| commands, of all variations, then insert
-the corresponding entry to that file. With |\citeindexfalse|, these
-entries will no longer be made.
-
-\head{Use with \texttt{chapterbib} package}
-
-The \thestyle\ package is compatible with the \texttt{chapterbib} package
-which makes it possible to have several bibliographies in one document.
-
-The package makes use of the |\include| command, and each |\include|d file
-has its own bibliography.
-
-The order in which the \texttt{chapterbib} and \thestyle\ packages are loaded
-is unimportant.
-
-The \texttt{chapterbib} package provides an option \texttt{sectionbib}
-that puts the bibliography in a |\section*| instead of |\chapter*|,
-something that makes sense if there is a bibliography in each chapter.
-This option will not work when \thestyle\ is also loaded; instead, add
-the option to \thestyle.
-
-Every |\include|d file must contain its own
-|\bibliography| command where the bibliography is to appear. The database
-files listed as arguments to this command can be different in each file,
-of course. However, what is not so obvious, is that each file must also
-contain a |\bibliographystyle| command, \emph{preferably with the same
-style  argument}.
-\head{Sorting and compressing citations}
-Do not use the \texttt{cite} package with \thestyle; rather use one of the
-options \texttt{sort} or \texttt{sort\&compress}.
-
-These also work with author--year citations, making multiple citations appear
-in their order in the reference list.
-
-\head{Long author list on first citation}
-Use option \texttt{longnamesfirst} to have first citation automatically give
-the full list of authors.
-
-Suppress this for certain citations with |\shortcites{|\emph{key-list}|}|,
-given before the first citation.
-
-\head{Local configuration}
-Any local recoding or definitions can be put in \thestyle\texttt{.cfg} which
-is read in after the main package file.
-
-\head{Options that can be added to \texttt{\char`\\ usepackage}}
-\begin{description}
-\item[\ttfamily round] (default) for round parentheses;
-\item[\ttfamily square] for square brackets;
-\item[\ttfamily curly] for curly braces;
-\item[\ttfamily angle] for angle brackets;
-\item[\ttfamily colon] (default) to separate multiple citations with
-     colons;
-\item[\ttfamily comma] to use commas as separaters;
-\item[\ttfamily authoryear] (default) for author--year citations;
-\item[\ttfamily numbers] for numerical citations;
-\item[\ttfamily super] for superscripted numerical citations, as in
-     \textsl{Nature};
-\item[\ttfamily sort] orders multiple citations into the sequence in
-     which they appear in the list of references;
-\item[\ttfamily sort\&compress] as \texttt{sort} but in addition multiple
-     numerical citations are compressed if possible (as 3--6, 15);
-\item[\ttfamily longnamesfirst] makes the first citation of any reference
-     the equivalent of the starred variant (full author list) and subsequent
-     citations normal (abbreviated list);
-\item[\ttfamily sectionbib] redefines |\thebibliography| to issue
-     |\section*| instead of |\chapter*|; valid only for classes with a
-     |\chapter| command; to be used with the \texttt{chapterbib} package;
-\item[\ttfamily nonamebreak] keeps all the authors' names in a citation on
-     one line; causes overfull hboxes but helps with some \texttt{hyperref}
-     problems.

+representative figure for the manuscript and the dynamic javascript plus
+HTML framework that allows for interactive control.
+
+An example of an interactive figure is a 3D model.
 The underlying figure is a X3D file while x3dom.js is the javascript driver
 that displays it. An author created interface is added via a html wrapper.
 The first 3D model published by the AAS Journals using this technique was
-\citet{2014ApJ...793..127V}.  Authors should consult the online tutorials
-for more information on how to construct their own interactive figures.
+\citet{2014ApJ...793..127V}.  
+
+Figure \ref{fig:interactive} provides an interactive example which can be
+run locally to demonstrate how a simple javascript plus html interface
+allows a reader to switch between figures. The necessary files for this
+particular interactive figure are in the {\tt\string interactive.tar.gz}
+file included with this package. Unpack the file and point the browser to
+the local html file. In this case, the javascript that runs the interactive
+buttons is embedded in the html file but it could just as easily be calls
+to external javascript libraries. Ideally, the javascript should be
+included with the submitted package of interactive files to minimize
+external dependencies within the published article.
 
-As with animations authors should include a non-interactive regular figure
-to use as an example.  The example figure should also indicate to the reader
-that the enhanced figure is interactive and can be accessed online.

+\section{IAU recommendations for nominal units \label{nominal}}
+
+The IAU 2015 resolution B3 defines nominal solar and planetary values by
+establishing conversions between solar and planetary values and SI units.
+The rational and specifications are given in \citet{2016AJ....152...41P}.
+The recommended nominal conversion constants for LaTeX have been
+incorporate into v6.3 to help authors follow the IAU resolution.
+
+The general commands take this form:
+

+4.&\verb+\nom{L}+& \nom{L}  &=&nominal solar luminosity\\

+units. These are:
+
+\vskip24pt
+\begin{tabular}{@{\vrule height 14pt depth 6pt width 0pt}llllp{3in}}

 %% Change Log
 ============================
+June 8, 2019
+Changed \author and \collaboration macros.
+Collaboration now takes two arguments:
+#1= number of authors to be listed before the
+name of the collaboration; #2 = name of the collaboration
+
+\nocollaboration{} has one argument, 
+#1= the number of authors above it that we want to print on the title page.
+
+June 6, 2019
+
+\acknowledgments does not use \begin{}...\end{} form,
+now just \acknowledgments command. Acknowledgments text
+ends with \par, so if author wants more than one paragraph
+in acknowledgment he/she should surround text with curly
+bracket:
+
+\acknowledgments
+text...
+
+or
+
+\acknowledgments
+{text...
+
+more text...}
+
+------
+
+
+============================
+June 3, 2019
+\let\footnote\onecolfootnote on page where references start, but
+before footnotes are entered,
+will allow footnotes to break in the right place (one column's width).
+
+============================
+May 15, 2019
+\centerwidetable is now \movetableover at Greg's suggestion.
