List of our observed compact groups, group coordinates, number of member galaxies, average redshift, and our group classification as described in the text.

Group dynamical properties.

Appendix A

We present here a set of figures representative of class A, class B groups.

thumbnail Fig. A.1

Stacked R band acquisition images for a sample of class A confirmed compact groups. From top left to bottom right, in increasing right ascension order: PCG001108+054449, PCG015254-001033, PCG102512+091835, PCG114233+140738, PCG151833-013726, and PCG235439+032308. The black lines visible in some images are the gap between the two CCDs on the EMMI red mosaic. In all cases the whole group was in one chip, but imaged at different rotation angles, to position accurately the slit. Exposure times vary from 180 s to 450 s. In all images N is up and E is left.
