Status of Clusters of Galaxies for Dynamics

The following table lists the various clusters of galaxies which J. Hill and W. Oegerle and collaborators are studying the dynamics by measuring galaxy redshifts with various multifiber systems. The table does not yet include clusters studied by other folks using the MX Spectrometer. N is the number of galaxies in the cluster with measured redshifts including ours and those from the literature. M is the number of those galaxies which are velocity members of the cluster. The table also lists the observed mean velocity of the cluster in km/sec.
