The NGC 507 cluster of galaxies.
Abstract
Redshifts and accurate positions for galaxies in the core of the NGC 507 group are presented. The group is shown to be closely similar to other groups of galaxies located nearby, including the Perseus cluster. A conventional virial analysis shows the usual excess kinetic energy. The redshift-magnitude diagram is consistent with the presence of bands.
