Top left: relation between asymmetry and Abraham concentration index. Red dots represent the early-type galaxies (E/S0, S0/Sa) classified with probabilities p₁  ≥  0.75, while the blue stars represent all late-type galaxies having p₂ probabilities above 0.5. Black crosses represent compact objects (all sources with CLASS_STAR  ≥  0.9). Open diamonds are sources with 0.5  <  p₁  <  0.75, which might be either ET/LT or mergers (see Sect. 3.2). The dashed line separates the areas where most of the early- and late-type galaxies are located (right and left area from the dashed line, respectively). Top right: relation between the smoothness and Abraham concentration index. The dashed line separates the areas where most of the early- (on the right; red dots) and late-type (on the left; blue stars) galaxies are located. Relation between the mean surface brightness and M₂₀ moment of light (middle left), and between the M₂₀ moment of light and Abraham concentration index (middle right). Symbols are the same as on the previous two plots. High probability regions of finding any of three morphological groups (early-, late-, or compact sources) have been defined in both plots. Bottom left: relation between the M₂₀ moment of light and Gini coefficient. See previous plots for symbols description. Bottom right: relation between the mean surface brightness and Gini coefficient. See previous plots for symbols description.
