Table 2: Main parameters for the groups candidates for our fields. Their identification codes show the average positions of the members. Mean redshifts (z) and average deviations are shown as velocities ( $\sigma$ ). The biweight estimators were used only in groups with at least 8 members. The group number identify member galaxies in the online table.
