A grid of model nebulae photoionized by a power-law continuum

A grid of self-consistent models for nebulae photoionized by power-law spectra is presented. The densities range from 102 to 106 cm-3. The power-law index of the radiation source varies from 2 to 0.7. The ''ionizing parameter'' U is generally chosen equal to 10-4, 10-3, 10-2. The abundances of the heavy elements in the nebular gas (C, N, O, Ne, Mg, Si, S, Cl, Ar, Fe are considered) range from twice solar to 1/50-th solar. Resulting intensities are presented for over 100 lines in the UV, optical and IR wavelength range (the accuracy being strongly dependent on the quality of the atomic data available). ''Mean ionic temperatures'' and ''mean ionic fractions'' are also given for ions of interest
