Abstract
:
A new empirical procedure is introduced to determine the confirmed galaxy members of a cluster. The method depends on both the projected distances of galaxies in the cluster field from the cluster centre and their radial velocities. Galaxies of the main body of the cluster are selected first, then the method works iteratively by increasing the standard values of the relative radial distance and velocity until all galaxies belonging to the cluster are included. The general apparent shape of the cluster will result from the distribution of the celestial coordinates of the cluster members.
