The dynamics of rich clusters - I. Velocity data

Abstract

Using the fiber-optic spectroscopy facility at the Anglo-Australian Telescope and the Automated Photographic Measuring machine at the Institute of Astronomy, Cambridge, 604 radial velocities and 501 stellar velocity dispersions for 40 galaxies in fields centered on 14 rich clusters from the southern cluster survey of Abell and Corwin (1983) are presented. The homogeneity of the data and the variety (in richness and morphological type) of the clusters are intended to facilitate intercomparisons of dynamical situations and the isolation of common phenomena. Good agreement is found with previous results. Show more
