Map of Coma cluster galaxies covered by MA08. Black crosses indicate galaxies fainter than M_B = −19 (the secondaries); circled dots: early-type primaries; dots in triangles: late-type primaries; bold circled crosses: NGC 4889 (left) and NGC 4874 (right). The inner (minor axis b =250 kpc) and outer (b =500 kpc) gray ellipses separate the central, inner and outer regions considered in the analysis. Primaries within the innermost ellipse (b =250 kpc) are excluded from the analysis. The rectangle indicates the area covered by the MA08 catalog which is relevant for density computations (Sect. 2.1).
