Star-forming galaxies in low-redshift clusters: data and integrated galaxy properties.

Abstract (from CDS):

This paper is a continuation of an ongoing study of the evolutionary processes affecting cluster galaxies. Both CCD R band and Hα narrow-band imaging was used to determine photometric parameters (mr, r24, Hα flux, and equivalent width) and derive star formation rates for 227 CGCG galaxies in 8 low-redshift clusters. The galaxy sample is a subset of CGCG galaxies in an objective prism survey (OPS) of cluster galaxies for Hα emission. It is found that detection of emission-line galaxies in the OPS is 85%, 70%, and 50% complete at the mean surface brightness values of 1.25x10–19, 5.19x10–20, and 1.76x10–20W/m2/arcsec2, respectively, measured within the R band isophote of 24mag/arcsec2 for the galaxy. The CCD data, together with matched data from a recent Hα galaxy survey of UGC galaxies within v≤3000km/s, will be used for a comparative study of R band and Hα surface photometry between cluster and field spirals.
