description

New redshifts are given for 21 clusters of galaxies from the Abell, Corwin, and Olowin Rich Cluster Catalogue. The redshift of the brightest cluster galaxy - where the brightest member is brighter than 15.5 - is employed as an indicator of the mean cluster redshift. The redshifts of first-, second-, and third-ranked galaxies are shown to agree, confirming the value of the survey procedure, although some clusters require more information than simply the redshift of the brightest cluster. 7 refs.
