Description of the columns: (1) Identification from Hickson (1993); (2) Alternative identification; (3) Right ascension (1950) from Hickson (1993); (4) Declination (1950) from Hickson (1993); (5) Morphological type, from Hickson (1993); (6) Systemic velocity from Hickson (1993), except for HCG 19c coming from NED; (7) Distance of the group. The distance has been computed from the mean redshift of the group extracted from Table 3 of Hickson et al. (1992). A Hubble constant of H0=75 km s-1 Mpc-1 has been used. To derive the distance we have used the method described in Paturel et al. (1997), i.e. the velocity of the group has been corrected to the centroid of the Local Group and for infall of the Local Group towards Virgo using an infall velocity of 170 km s-1; (8) Asymptotic magnitude corrected for internal and external extinction, from Hickson (1993); (9) Optical radius in arcsec, from NED; (10) Optical radius in kpc, using Cols. (7) and (9).
