Readme file for the files containing the ultraviolet spectra described in
Leitherer, Robert, & Heckman (1995; ApJS, 99, 173)

There are 144 tables. Each table has 4 columns with 860 lines and contains the
synthetic ultraviolet spectrum from 1205 A to 1849 A as discussed in the paper.
The first column gives the age in yr, column 2 is the wavelength in Angstrom,
column 3 is the luminosity [erg/sec/Angstrom], and column 4 is the normalized
spectrum. (Column 4 contains what is plotted in the figures of Leitherer et al.
(1995))

The filename uniquely identifies the starburst models. 
The nomenclature is Ti_j_k_p00.x. p00 stands for `plus 0.0', indicating a
metallicity of solar. Future models will have non-solar abundances.

i is from 10 to 90 at intervals of 10, indicating an age of 1.0 to 9.0 Myr;
j is 30, 40, 60, 80, and 100, indicating an upper cut-off mass from 30 
  to 100 M_sun;
k is 150, 235, 300, and 375, which stands for IMF exponents of 1.50, 2.35,
  3.00, and 3.75;
x is b or c, indicating a burst (b) or continuous star formation (c).

There are 8 combinations of cut-off masses and IMF exponents for each of the
9 timesteps so that there are 2 x 9 x 8 =144 files for the two star formation
laws (burst and continuous).  

Example:  t30_80_375_p00.b contains the spectrum for a burst of age 3 Myr,
          M_up of 80, IMF exponent of 3.75, and solar metallicity.
