Pre-run grids are available for photoionization models with
ionization parameters ranging from q=5e6 to 3e8 cm/s, and
metallicities from Z=0.05 to 3 solar.
We ran these models for
the two limiting cases of instantaneous and continuous star formation.
Two values for electron density were used; 10 and 350 electrons per cubic
centimeter. We used the ionizing radiation fields from stellar population
synthesis models Starburst99
and Pegase.
The grid metallicities are limited by the stellar population
synthesis models.
The resulting photoionization grids are suitable for the interpretation
of emission-line spectra from HII regions and star-forming galaxies.

These models were run by Lisa Kewley. The instantaneous burst models are explained in:

Dopita et al. 2000, ApJ, 542, 224.

The continuous starburst models are described in:

| The grids available for downloading (see table below) include the
results from every ionization parameter and metallicity used in the
two papers above. |
