================================================================================
The file nebular_emission_gutkin16.tar.gz in this directory contains the 
values of some of the most commonly used optical and ultraviolet emission-lines
predicted by models of nebular emission from star-forming galaxies
(presented in Gutkin et al. 2016).
These models have been computed combining the latest version of the stellar
population synthesis code of Bruzual & Charlot (2003; Charlot & Bruzual, in 
preparation) with the latest version of the photoionization code CLOUDY 
(Ferland et al. 2013)

********************************************************************************

nebular_emission_gutkin16.tar.gz contains 14 files, each corresponding to given
value of the interstellar gas metallicity Zism, specifically:

Zism= 0.0001, 0.0002, 0.0005, 0.001, 0.002, 0.004, 0.006, 0.008, 0.010, 0.014, 
0.017, 0.020, 0.030, 0.040

The file names are built as follows:
nebular_emission_Zaaa.txt, where aaa are the digits after the decimal point of the 
value of the interstellar gas metallicity, for example: 
nebular_emission_Z017.txt corresponds to Zism=0.017

Each model file contains 23 columns:

col.1: log(Us), logarithmic value of the ionization parameter

col.2: xid, dust-to-metal mass ratio

col.3: nh, hydrogen gas density (per cubic cm)

col.4: (C/O)/(C/O)sol, carbon-to-oxygen abundance ratio in units of the solar
value, (C/O)sol=0.44

col.5: mup, upper mass cutoff of the IMF 

cols 6-23: predicted intensities of 18 optical and ultraviolet emission lines 
(in units of solar bolometric luminosity [3.826E+33] per unit SFR [in Mo/yr]) 
for constant SFR with a Chabrier (2003) IMF sustained for 10^8 yr, specifically:

[OII]3727 Hbeta [OIII]4959 [OIII]5007 [NII]6548 Halpha [NII]6584 
[SII]6717 [SII]6731 NV1240 CIV1548 CIV1551 HeII1640 OIII]1661 OIII]1666 
[SiIII]1883 SiIII]1888 CIII]1908
