 This is emulateapj.cls, version February 19, 2025
 For the latest version check http://hea-www.harvard.edu/~alexey/emulateapj

 NOTE: ApJ has moved its publishing to IOP and they have slightly changed
 the formatting. To implement these changes, call emulateapj with the iop
 option, as in
 \documentclass[iop]{emulateapj}

 Other available options:

 [chicago] - (default) typeset as was done in the University of Chicago Press
 [twocolumn] - (default) two-column mode
 [onecolumn] - main text in one-column mode
 [apj]       - typeset as for main journal
 [apjl]      - (default) typeset as for ApJ Letters 
 [tighten]   - some adjustments to approximate grid typesetting
 [numberedappendix]   - number appendix sections as A, B, etc
 [appendixfloats]  - use separate numbering for floats within appendix
 [twocolappendix]  - make appendix in two-col mode in a two-col paper
 [revtex4]   - force using revtex4
 [astrosymb] - load Astrosymb font and define \astro commands from aastex

 NOTE 2: Starting from version 11/10/2009, emulateapj tries to load
 revtex4-1 if present on the system. This may cause small changes in
 typesetting for old documents. Also, revtex4-1 does not interact
 well with the lscape package which is needed for typesetting of
 long rotated tables. If you want full compatibility, please
 download the last version based on revtex4,
 http://hea-www.harvard.edu/~alexey/emulateapj/emulateapj-rtx4.cls
 and bundle it with your TeX source code. Starting with the
 8/17/2012 version, you can also use the [revtex4] option.

 `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.
 
 If a manuscript is prepared for ApJ submission using the standard
 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.
