Dynamics of cD clusters of galaxies. I. Redshift data for seven clusters HILL J.M., OEGERLE W.R., <Astron. J. 106, 831 (1993)> =1993AJ....106..831H (SIMBAD/NED Reference)
ADC_Keywords: Clusters, galaxy; Spectroscopy; Radial velocities 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. File Summary:

Note (1): A letter "E" in the comments field means that the velocity was derived from emission lines only. For galaxy 388 in table4, the listed velocities were derived from emission and absorption lines separately. The letter "A" indicates the presence of absorption lines in the higher Balmer lines. The number of independent measurements contributing to the combined velocity of the cD are also reported. The identifying number of each cD galaxy is 201, except for the A399 cD which is 448 in table4
