Notes. Columns: (1) HCG ID number, (2) right ascension, (3) declination, (4) distance calculated by Jones et al. (2023), (5) the evolutionary phase of the group as originally proposed by Verdes-Montenegro et al. (2001), (6) redshift (Hickson et al. 1992), (7) core members of the group, (8) morphological types from the table compiled by Jones et al. (2023), most of which were taken from Hickson et al. (1989), (9) H I content based on the analysis of VLA archival data by Jones et al. (2023); the deficiency for each group was estimated based on the logarithmic difference between the predicted H I mass from a B-band luminosity scaling relation (L_B − M_HI) of isolated galaxies and the observed H I mass.
