^a Taken from Hickson (1993) and from NED database for NGC 92. Morphological type for NGC 92 was taken from Prugniel et al. (1998).
^b Distances were obtained using the redshift for each group given in Hickson (1992) and assuming the groups follow the Hubble flow. For NGC 92, we used the mean redshift of the group members. For each galaxy, redshift was taken from NED. In all cases, we used H₀ = 70 km s^-1 Mpc^-1, $\Omega_{\rm m}$ = 0.3 and $\Omega_{\lambda}$ = 0.7.
^c Systemic velocity deduced from our velocity field analysis.
^d For HCG 2a, b, c, HCG 7a, d, HCG 22c, and values of PA were taken from Mendes de Oliveira (1992). These were determined at semimajor axis lengths of 2 h^-1 kpc for all Hickson group galaxies with $z \leq 0.05$ . For NGC 92 the PA was taken from the Hyperleda database.
^e Taken from the Hyperleda database. PA is the position angle of the major axis at the 25 mag arcsec^-2 isophote, in the B-band.
^f Taken from Mendes de Oliveira et al. (2003).
^g Taken from Plana et al. (2003).
