HII regions in NGC 5055. II. Physical Properties

Abstract

In this paper, using CCD observations of the galaxy NGC 5055 in the emission lines of H\alpha and H\beta (Rozas 2007), together with CCD observations in the narrow- band filters of [OII], [OIII], [SII], and S[III] lines we have calculated the equivalent widths, excitations, ionization hardness, ionization parameters and metallicities for the regions catalogued in Rozas (2007).
