%% This is emulateapj.cls, version Sept 8, 2003
%% For the latest version check http://hea-www.harvard.edu/~alexey/emulateapj
%%
%% 2/9/03: MAJOR CHANGE: This is a complete rewrite of emulateapj.  It adds
%% the use of single-column floats (figures, tables and footnotes) in the
%% two-column mode.  All standard LaTeX/AASTeX environments such as
%% {figure}, {table}, {figure*}, {table*} and {deluxetable} (and
%% {deluxetable*} added here) should work as expected. Enjoy. 
%%
%%
%% `emulateapj' is a LaTeX2e class to emulate the Astrophysical Journal
%% (ApJ) page layout. The page length of the resulting document is very
%% close to that in ApJ when Times fonts are used instead of the LaTeX
%% default CM fonts (see below).
%% 
%% If a manuscript is prepared for ApJ submission using the standard AAS
%% (American Astronomical Society) LaTeX macros and the `aastex' style (see
%% instructions for authors on the ApJ web site), the only thing required
%% from the user should be to replace \documentclass{aastex} with
%% \documentclass{emulateapj}, and perhaps resize figures as desired and
%% replace {deluxetable} with {deluxetable*}
%% (possible minor problems are described below).
%%
%% emulateapj requires revtex4.cls. If you don't have it already, it can be
%% downloaded from http://publish.aps.org/revtex4/ (it's a small package).
%% Other extrnal packages used are latexsym, graphicx, amssymb, longtable,
%% epsf. They should already be present in the modern TeX distributions; if
%% not, download them from www.ctan.org.
%%
%% To switch to the Times font, use the accompanying file apjfonts.sty (see
%% the site above):
%% \usepackage{apjfonts}. Alternatively, e.g., use the standard
%% \usepackage{mathptmx}, the only difference is in math and Greek symbols.

%% Release notes (02/09/03):
%% 
%% 1) This is a complete rewrite of emulateapj. The package is now
%% based on revtex instead of aastex + multicol. Some inconsistencies with
%% aastex may have been missed, so please don't hesitate to report them.
%%
%% 2) The {deluxetable} environment is re-implemented (the problem with the
%% the aastex's deluxetable is it does not float). There is also a new
%% environment {deluxetable*} (absent in aastex) to set a floating table
%% two-column wide. These were not thoroughly tested, so please report any
%% problems. Known problems:
%%   (a) \rotate doesn't work (too difficult to implement). Place the table
%% at the end of the paper after references, inside {turnpage} environment
%% (\begin{turnpage}\begin{deluxetable} ... \end{deluxetable}\end{turnpage})
%%
%% 3) Multi-page tables cannot be set properly inside the main text; you
%% need to move the table to the end of the paper (after the references) and
%% issue the command \LongTables before it.
%% 
%% 4) By default, deluxetables are typeset with \footnotesize. If you want
%% to use a different size, use, e.g., \tabletypesize{\normalsize} _outside_
%% the deluxetable environment. If you need to increase interline spacing
%% in the tables, use \def\arraystretch{1.XXX} also _outside_ deluxetables.
%% 
%% 5) Option `onecolumn' (as in \documentclass[onecolumn]{emulateapj})
%% sets the whole paper (except the reference section) in one column
%% as done by the ApJ for papers with long equations.
%% 
%% 6) Options `apj' and `apjl' (\documentclass[apj]{emulateapj}) change the
%% spacing of the references (the default is ApJL wide spacing). 
%%
%% 7) By default, appendix subsections are not numbered:
%%             APPENDIX
%%      Derivation of Equations
%% If you want them numbered (`A. Derivation of Equations'), use the option
%% \documentclass[numberedappendix]{emulateapj}
%%  
%% 8) By default, the comment in the upper-left corner of the title page and
%% under the abstract will say "Draft version \today". There are additional
%% commands \journalinfo{} and \submitted{} (the latter is equivalent to the
%% aastex \slugcomment{} which also works) to change those comments. Used
%% alone, \submitted{} will act on both those places.
%% 
%% 9) The \title command sets the entire title, including math, in upper
%% case. If this is undesirable, use \lowercase{} macro, e.g., 
%% \title{UPPER CASE OK HERE \lowercase{$a+b=c$}}.
%%
%% 10) On the last page where the references start, there may be problems
%% with placement of footnotes. There is a command \lastpagefootnotes which
%% can be issued somewhere before those footnotes. It will result in the
%% remaining footnotes set together at the end of the text, properly
%% adjusted.
%% 
%% 11) There may be problems with single-column figure placements on the
%% last page; try moving the figure around or explicitly specifying [t]
%% placement.  There may also be minor column misalignments on
%% complicated pages with footnotes, sections, etc.; these are too difficult
%% to fix.
%%
%% 12) Any footnotes in the paper title should be set as
%% \title{Title\footnotemark[1]} \footnotetext[1]{text} (with foootnotetext
%% outside the title), rather that simply a \footnote{}.
%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%% changes since 2/9/3: 
%% 
%% 2/14/3: fixed several bugs in deluxetable and footnotes inside the title.
%%
%% 3/3/3:  Table caption is made in two lines. works only in {table} or
%% {table*}, but not in {deluxetable}
%%
%% 3/3/3:  Redefine p@subsection etc. for ApJ-style cross-references.
%%
%% 3/16/3:  Define \tablerefs
%%
%% 3/25/3:  Fix two-column references in the onecolumn mode (see 
%%          \set@column@hsize{2})
%%
%% 4/9/3:  Change the definition of \tablenotemark. It is less general but
%%         works in the table caption. Also, put the body of deluxetable*
%%         inside a minipage to fix table footnotes.
%%
%% 5/14/3: Change section title font sizes. They are now different for 'apj'
%%         and 'apjl' options
%%
%% 7/8/3:  redefine NAT@sort@cites after loding revtex4 to prevent citations
%%         from being sorted
%%
%% 7/15/3: Fix \and in the author list
%%
%% 7/17/3: Make \colhead to center column titles by default
%% 
%% 7/27/3: Redefile \@biblabel to remove the numbered list from thebibliography
%%
%% 9/08/3: Further fixes to cutinhead: define @ptabularcr and use LT@cols
