This directory contains: README - this file emulateapj.sty apjfonts.sty `emulateapj' is a LaTeX (209 or 2e) style to approximate the Astrophysical Journal (ApJ) page look. The page length of the document is close to that in ApJ if postscript Times fonts are used instead of the standard CM fonts (see below). `emulateapj' requires the `multicol' package available from CTAN archives. The file emulateapj.sty is a modification of the AAS (American Astronomical Society) preprint style aaspp4.sty, including pieces of the plain TeX apjformat* by someone BLW. If a manuscript is prepared using the standard AAS macros used for electronic manuscript submission, the only thing required from the user is to replace the style `aaspp4' with `emulateapj' in the first line of the document. We tried not to touch any of the nonobvious aaspp4 functionality to save trouble for users, so large parts of the code are probably useless, of which we did not care. Because `multicol' package cannot deal with floats of the width of the single column, footnotes, figures, tables etc. can only be set across two columns (that is, use `figure*' environment instead of `figure'.) Alternatively, insert figures as non-floats in the exact place of the text by hand. There is a command \submitted{your text} to replace the default text in the upper left corner of the front page ("Draft version \today") with `your text'. Use it before the title commands. There is a package option `onecolumn' (available only in LaTeX2e), \usepackage[onecolumn]{emulateapj}, which sets the whole paper in one column mode as is done by the ApJ for papers with lengthy equations. Even if the document is `onecolumn', `thebibliography' or `references' are typeset in two columns. For users of `deluxetable': in LaTeX2e, the table font size is not reduced by putting fontsize commands inside \begin{deluxetable} and \end{deluxtable}. To reduce the font size, \tablefontsize command is defined. To use, put e.g., \tablefontsize{\footnotesize} after \begin{deluxetable}. The latest version of emulateapj.sty is also available from http://hea-www.harvard.edu/~alexey/emulateapj/ To use Times postscript fonts, also use the accompanying file apjfonts.sty (at the site above, there is also a package of font files if necessary).
