All Tables

Table 1: Observing log.
Table 3: Classification of the DPOSS II compact groups and neighbouring large scale structures. n represents all galaxies which fulfilled the velocity criteria, irrespective of the original catalogue of group galaxies, while the number quoted in parentheses is the number of concordant galaxies that were originally part of the DPOSS catalog. When a (2+2) is given for n (members), it means that the candidate group is composed of two concordant pairs of galaxies.
Table 4: Morphological classification of the member galaxies for groups of class A and B. $T_{\rm spectrum}$ is the morphogical type of the group as defined by the percentage of galaxies with EW(H $\alpha)~>~6$ $\AA$ .
Table 5: Group dynamical properties. $\sigma _{r}$ , R, and $H_{\rm0}t_{\rm c}$ are expressed in logarithmic values; mass, luminosity, and mass-to-light ratio are given in solar units. The symbols follow Hickson et al. (1992).
Table 2: Observed compact groups candidates from the DPOSS survey. Column 5 lists the kind of spectrum for each galaxy: abs means a spectrum which is dominated by absorption lines; em means a spectrum dominated by emission lines and mix a spectrum where both emission and absorption lines are present. The most significant emission lines have been listed for the observed galaxies.
