\tablefoot {Columns are the
following: 1) group ID; 2) RA; 3) declination; 4) redshift; 5) number of detected members; 6)
l.o.s. velocity dispersion~$\sigma$; 7) possible high purity. RA and
declination are in degrees and $\sigma$ in km~s$^{-1}$. RA, declination and
redshift are the median values of all the galaxies in each
group. The star near the group ID label those groups found by the algorithm 
also when using only galaxies with flag~3 and~4 (see text for further details). 
Column~7 labels with an ``H'' those groups detected by the
algorithm also with the {\it high-purity} set of parameters. See the electronic edition
for the complete list of VVDS-02h groups.}
