Current Status of the ACO Cluster Redshift Compilation
Abstract
Description
We present an update of our compilation of measured redshifts of galaxy clusters in the all-sky Abell catalog. In the last 7 years the number of ACO clusters with measured z has doubled to now ~2100, but still ~56% of these are based on only 1 or 2 measured member galaxies. Our October 1997 version gives 2247 redshifts (including components or line-of-sight superpositions) for 2114 distinct A- and S-clusters. Velocity dispersions are listed for 536 different ACO clusters (613 subclusters) and the median is 695 km/s. We mention some applications of our compilation for determining the large-scale structure of the nearby Universe.
