Description of the columns: (1)  {Identification from
Hickson (\cite{hic1993})}; (2)  {Alternative identification}; (3)
{Right ascension (1950) from Hickson (\cite{hic1993})}; (4)
{Declination (1950) from Hickson (\cite{hic1993})}; (5)
{Morphological type, from Hickson (\cite{hic1993})}; (6)
{Systemic velocity from Hickson (\cite{hic1993}), 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. (\cite{hic1992}). A Hubble constant of
$H_{0}=75$~km~s$^{-1}$~Mpc$^{-1}$ has been used. To derive the
distance we have used the method described in Paturel et~al.
(\cite{pat97}), 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 (\cite{hic1993})}; (9)~{Optical radius in
arcsec, from NED}; (10)~{Optical radius in kpc, using
Cols.~(7) and~(9).}
