2008A&A...486..755T Star-forming galaxies in low-redshift clusters: data and integrated galaxy properties Thomas, C. F.; Moss, C.; James, P. A.; Bennett, S. M.; Aragon-Salamanca, A.; Whittle, M. Abstract. Aims. This paper is a continuation of an ongoing study of the evolutionary processes affecting cluster galaxies. Methods: Both CCD R band and H{alpha} narrow-band imaging was used to determine photometric parameters (m_r_, r_24_, H{alpha} 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 H{alpha} emission. Results: 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 1.25 x 10^-19^, 5.19 x 10^-20^, and 1.76 x 10^-20^ W m^-2^ arcsec^-2^, respectively, measured within the R band isophote of 24 mag arcsec^-2^ for the galaxy. Conclusions: The CCD data, together with matched data from a recent H{alpha} galaxy survey of UGC galaxies within v <= 3000 km s^-1^, will be used for a comparative study of R band and H{alpha} surface photometry between cluster and field spirals. Key words: galaxies: clusters: general, galaxies: evolution, galaxies:, interactions
