The Physical Reality Of McConnachie compact groups of galaxies –II.

The McConnachie compact groups of galaxies (McConnachie et al.2009) has been revised by using The tree clustering technique (The Astrophysical Euclidean Separation Coefficients ). The first 92 groups containing five individuals have been adopted for the present investigation. Calculation have been performed to derive, for each group, the average astrophysical euclidean separation coefficients between each astrophysical parameter of the members. The results show that , there are many galaxies should be rejected from its groups and some groups have sub- groups and paired. The tables of groups and their members are included.
