1993AJ....106..831H DYNAMICS OF cD CLUSTERS OF GALAXIES. I. REDSHIFT DATA FOR SEVEN CLUSTERS JOHN M. HILL Steward Observatory, University of Arizona, Tucson, Arizona 85721 Electronic mail: jhill@as.arizona.edu WILLIAM R. OEGERLE Goddard Space Flight Center, Code 681, Greenbelt, Maryland 20771 Electronic mail: oegerle@stsci.edu Received 1993 April 28 revised 1993 May 17 ABSTRACT We present the initial results of a spectroscopic study of a sample of cD galaxy clusters. The goal of this program is to study the dynamics of the clusters, with emphasis on determining the nature and frequency of peculiar velocity cD galaxies. In this paper we present redshifts for 611 galaxies in the fields of the rich Abell clusters A193, A399, A401, A1795, A1809, A2063, and A2124. We discuss our data reduction techniques, and compare our derived velocities with previously published values. We find a frequency of emission line galaxies of ~6% in clusters, a factor of 2-3 less than the field.
