* color PostScript file


A set of files that can be used to generate PostScript files like
those listed above is packaged in a compressed tar file called
FES_V4_TAR.Z for UNIX users and in a BACKUP file called FES_V4.BCK
for VMS users.  Once the relevant file has been downloaded, it can be
unpacked as follows: 

	$ backup fes_v4.bck/save *		(in a VMS environment)

or

	% mv fes_v4_tar.Z fes_v4.tar.Z	        (in a UNIX environment)
	% uncompress fes_v4.tar
	% tar xvf fes_v4.tar

All or part of the Explanatory Supplement can be reconstituted
beginning with the DVI file FES.DVI and the
Encapsulated Postscript files (i.e., files with extension .EPS)
corresponding to the relevant figures. A PostScript file containing
any part of the document can be generated with the VMS command 

	$ dvips/start=xxx/last=yyy/output=zzz FES

where xxx is the starting page number (defaults to page 1), yyy is the
last page number (defaults to last page of document), zzz is the
filename for the PostScript file (defaults to FES.PS), 

or the analogous UNIX command

	> dvips -pp xxx-yyy -o zzz FES

Alternatively, the Explanatory Supplement can be reconstituted in its
entirety by processing the LaTeX manuscript FES.TEX.
Files with .TOC, .LOT, .LOF, and .EPS extensions enable incorporation
of the preprocessed Table of Contents, Lists of Tables and Figures,
and the Encapsulated figures, respectively.  The AASTEX STY files are
included in the package in case they are not already available in your
LaTeX installation. 

LaTeX files corresponding to individual sections are also provided and
may be processed as follows. First, uncomment the lines beginning with
"%%\" at the top of the FES_SEC_?.TEX file
(i.e., remove the "%%"). Second, follow the directions at the end of
the file to add an "\end{document}" statment and delete the "\newpage"
statement. Third, place the FES_MACROS.TEX
file, any required Encapsulated PostScript files (corresponding to
figures), and, if necessary, the EPSF.STY file, in the same directory
as the FES_SEC_?.TEX file. Finally, process
the document. Note that cross-references to other sections will be
incorrect if you print a section as a stand-alone document. 

Appendix files with a .TEX extension can be processed similarly. 
However, those ending in .TXT are flat ASCII files and thus do not 
require processing prior to printing.
