It has resisted both a global and precise physical interpretation despite a consequent number of works, observational, theoretical or using numerical simulations. It appears that its precise properties depend on the population of galaxies in study. Instead of selecting a priori these populations, we propose to objectively construct homologous populations from multivariate analyses. We have undertaken multivariate cluster and cladistic analyses of a sample of 56 low-redshift galaxy clusters containing 699 early-type galaxies, using four parameters: effective radius, velocity dispersion, surface brightness averaged over effective radius and Mg2 index. Description: We thus chose the data compiled and standardized by Hudson et al. (2001, Cat. J/MNRAS/327/265) for 699 early-type galaxies in 56 clusters, in the redshift range from 0.007 to 0.053 (Streaming Motions of Abell Clusters (SMAC) catalogue). File Summary:

Note (1): See section 3.2 and Figure B1 for further details. Figure B1: Cladogram obtained with four parameters. It is a majority rule consensus of 986 equally parsimonious trees. The branches are coloured according to the value of Mg2 (from dark blue to yellow through green as Mg2 increases). The outer annulus is formed by the names of the galaxies, with colours according to the group (numbered from C1 to C7) as detailed in Table c1. Note (2): From Hudson et al., 2001, Cat.
