H-II REGION POPULATION IN A SAMPLE OF NEARBY GALAXIES WITH NUCLEAR ACTIVITY .2. LUMINOSITY FUNCTION, SIZE, AND RADIAL DISTRIBUTIONS

This paper presents the second part of an extensive study of the prope rties of the H II region population in a sample of spiral galaxies wit h active nucleus. This study comprises some 2000 H II regions, distrib uted in 27 out of the 55 galaxies in the original sample, observed in narrow-band H alpha CCD imaging. About 70% of these H II regions are c alibrated in absolute flux. We present the luminosity function, size d istribution, the relationship between the H alpha flux and the size, t he emission measure, and the radial distribution of the H II regions i n each galaxy. We analyze the main properties of the H II regions atte nding to the Hubble type and to the level of nuclear activity of the h ost galaxy.
