Description
Optical spectroscopy of 93 galaxies, 60 projected in the direction of Abell 1367, 21 onto the Coma cluster and 12 on Virgo, is reported. The targets were selected because they were detected in previous H{alpha}, UV or r' surveys. The present observations bring to 100% the redshift completeness of H{alpha} selected galaxies in the Coma region and to 75% in Abell 1367. All observed galaxies except one show H{alpha} emission and belong to the clusters. This confirms previous determinations of the H{alpha} luminosity function of the two clusters that were based on the assumption that all H{alpha} detected galaxies were cluster members. Using the newly obtained data we re-determine the UV luminosity function of Coma and we compute for the first time the UV luminosity function of A1367.
