Scientific paper

A composite model for the narrow emission line region of AGN is presented, assuming an outwards motion of the emitting filaments through a dilute medium. The effects of the shock front and of a central source radiation act on the opposite edges of the single filaments. The input parameters are: the preshock density, nzero; the velocity of the filaments, nuzero; the spectrum of the continuum radiation for which a power law is adopted; and the cut-off at high energies, Ec. The results obtained by the ejection model confirm two main types of AGN (shock dominated and radiation dominated), as found by the infalling model of Paper I. However, some groups of AGN which were ambiguously identified in Paper I are definitively characterized in the ejections case. Assuming nzero is equal to 300 per cu cm, and alpha is equal to 1.5, the observed emission line spectra can be fitted by a radiation flux intensity of less than 10 to the 13th and a filament velocity in the range 150-300 km/s. A high energy cutoff of less than 500 eV characterizes some NLR spectra, in particular, NLR from QSO.
