Distributions, equivalent widths and metallicities of the H II regions in the spiral galaxies NGC 5457 and NGC 4395.
CEDRES B. and CEPA J.
Abstract (from CDS):
Using CCD observations in the narrow band filters in Hα, Hβ, [OII], [OIII], [SII] and [SIII] lines we have compiled a catalogue of 338 HII 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.
