Descripción
Using CCD observations in the narrow band filters in Hα , Hβ
, [O Ii], [O Iii], [S Ii] and [S Iii] lines we have compiled a catalogue
of 338 H Ii regions for the inner parts of NGC 5457 and 158 for NGC
4395. The extinction, equivalent widths, distributions, excitations,
ionization hardness, ionization parameters and metallicities for these
regions, a distinction being made between arm and inter-arm zones, are
presented here with the first results of a study of stellar formation.
