J/A+A/490/923  Morphology of galaxies in Coma cluster direction (Michard+, 2008)

Morphology and membership of galaxies in the Coma cluster direction, down to MB=-14.25. I. A catalog of 473 members. Michard R., Andreon S. <Astron. Astrophys. 490, 923 (2008)> =2008A&A...490..923M

We have examined 1155 objects from the GMP 1983 catalogue on B and V images of the CFH12K camera, and obtained the Hubble type in most cases. Coma cluster membership for 473 galaxies has been derived using morphology, apparent size and surface brightness, and, afterward, redshift. The comparison between morphology- and redshift- memberships and of luminosity functions derived from this morphologically-selected sample, or using statistical members or spectroscopic members, both show that the morphological membership provided here can be trusted. For the first time the morphological classification of Coma galaxies reaches faint enough magnitudes to observe the whole magnitude range of the giant types, E, S0 and spiral stages. The data presented in this paper makes our sample the richest environment where membership and morphology for complete samples down to faint magnitudes (MB~-15mag) are available, hence enlarging the baseline of environmental studies.
