Abstract
Recent observations of the Coma cluster of galaxies in its central reg ion have provided approximately 250 new redshifts - allowing a good me mbership criterion to be established for brighter galaxies - and magni tudes for 8000 objects in the same region derived from photometric dat a complete up to V-26.5=22.5. A thorough structural study of the galax y distribution of the cluster galaxies, jointly with an X-ray wavelet analysis, and with a kinematical analysis of the velocity distribution allows us to uncover a primary body of the cluster, with evidence for a velocity gradient.
