1) FILES:
=========

General nomenclature of filenames:
	ezzz_imf_mup_sfh.n
Where:
	e       Indicates high mass-loss tracks
	zzz	Metallicity 	(e.g. 020 for Z=0.020)
	imf	Slope of IMF	(     235     alpha=2.35=Salpeter)
	mup	upper mass cut-off of IMF
				(     120     120 Msun)
	sfh     code for starformation history:
		- isb	instantaneous burst
		- dt1	extendend burst of duration 1 Myr
		- dt2...   "        "   "     "     2  "
		- cs1	constant star formation (ages 0-10  Myr)
		- cs2	constant star formation (ages 0-100 Myr)
	n	number of output file:
		- 20    Main output file         (--> results in SV98)
		- 21    Output file for WR lines (--> results in SV98)
		- 23    Colors of integrated population

Each file contains a header including detailed information about
all the adopted input parameters, the content of the files and the
output units used.

File *.23 (photometry):
~~~~~~~~~~~~~~~~~~~~~~~~

Broad-band colors of stellar population. The colors include the
nebular continuous emission, but neglects the contribution of
all nebular and stellar emission lines.
The filter response curves and calibration of Leitherer & Heckman
(1995, ApJS, 96, 9) are used.
