Morphological classification and structural parameters of galaxies in the Coma and Perseus clusters
Abstract
We present the results of an isophotal shape analysis of galaxies in the Coma and Perseus clusters. These data, together with those of two previous papers, provide two complete samples of galaxies with reliable Hubble types in rich clusters: 1) all galaxies brighter than m_b = 16.5 falling within one degree (=2.3 Mpc) from the center of the Coma cluster (187 galaxies), 2) all galaxies brighter than m_Zwicky=15.7 in a region of 5 degr 3' times 5 degr 27' around the center of the Perseus cluster (139 galaxies). These two complete samples cover 5 orders of magnitude in galaxy density and span areas of 91 and 17 Mpc^2, clustercentric radii up to 6.4 and 2.3 Mpc, for Perseus and Coma respectively. They will be used in subsequent papers to study the dependence of galaxy types on cluster environment and as reference samples in comparisons with distant clusters. Based on observations made with the 2-meter Telescope Bernard Lyot of Pic-du-Midi Observatory, operated by INSU (CNRS) and the Schmidt telescope at the Calern Observatory (OCA).
