Abstract
A grid of composite models for the narrow-line region of active galaxies, which consistently account for both the effect of a photoionizing radiation from the active center and of a shock front, is presented. Theoretical results, calculated with the SUMA code, are given for different values of shock velocities, preshock densities, geometrical thickness of the clouds, and, particularly, for the ionizing radiation intensity in a large range. The input parameters are chosen within the ranges indicated by previous fits of several observed emission-line and continuum spectra from active galaxies. Shock velocities from 100 to 1500 km s-1 and preshock densities from 100 to 1000 cm-3 are considered. The line intensities of the most important ultraviolet, optical, and infrared transitions are obtained and are listed in several tables.
