Notes. Column (1): group number. Column (2): Galaxy member of the group. Column (3): morphological type taken from Hickson (1993). Column (4): B-band absolute magnitude. Column (5): isophotal radius at the limiting surface brightness of 25 B mag arcsec^-2, Column (6): observed rotational velocity at R₂₅. Column (7): maximum radius reached by the rotation curve. Column (8): observed maximum rotational velocity. Column (9): rotational velocity at R₂₅ derived from the arctan model. Column (10): rotational velocity used in the TF relation. Column (11): quality flag on  (1: reached; 2: probably reached; 3: probably did not reach; 4: did not reach).
