Abstract (from CDS):

The identification of young star groupings (YSG) in the three spiral galaxies NGC 3377A, NGC 3507, NGC 4394 is obtained by mean of the statistical method described in Paper I. We find 83, 90, 185 YSGs, respectively. An identification map of YSGs, as well as their size distribution, their B-luminosity function and their surface luminosity density radial behaviour are presented and compared. These data, in addition to those in Paper I, constitute a first sample suitable for seeking correlations among properties of galaxies and their YSGs, which we briefly discuss here.
