Abstract:
This paper presents the second part of an extensive study of the properties of the H II region population in a sample of spiral galaxies with active nucleus. This study comprises some 2000 H II regions, distributed in 27 out of the 55 galaxies in the original sample, observed in narrow-band Hα CCD imaging. About 70% of these H II regions are calibrated in absolute flux. We present the luminosity function, size distribution, the relationship between the Ha flux and the size, the emission measure, and the radial distribution of the H II regions in each galaxy. We analyze the main properties of the H II regions attending to the Hubble type and to the level of nuclear activity of the host galaxy.
