Notes. Columns: (1) name in HCG catalogue, (2) other name, (3) right ascension (J2000), (4) declination (J2000), (5) morphological type, from HyperLeda (http://leda.univ-lyon1.fr/), (6) heliocentric velocity from optical spectra (references below), (7) optical isophotal diameter at 25 mag arcsec2 in B-band (from RC3 de Vaucouleurs et al. 1991, unless indicated otherwise), (8) logarithm of B-band luminosity calculated following Fernández Lorenzo et al. (2012) with values from HyperLeda and the morphologies and velocities given in this table, the quoted errors ignore distance uncertainty (±0.05 dex).
