Notes. (1)–(4) Galaxy name, RA, Dec, and heliocentric velocity were taken from Christlein & Zabludoff (2003). (5) Ratio of the projected distance from the cluster centre and virial radius of the cluster (Rvir = 1.6 Mpc). (6) and (7) g-band total magnitude, (g − r) colour, corrected for Galactic extinction (Schlegel et al. 1998). (8) Morphological type (from the NED). (9) Alternative galaxy name.
