Left: the ratio between half mass and half light radius (a/ a) with the Hubble type (left). Big colored dots represent the averaged a/ a in each Hubble type bin, and the lines the dispersion. Stars and big circles show the results obtained with the GMe and CBe bases, respectively. Right: a/ a as a function of the galaxy stellar mass. The black crosses show the averaged correlation independent of the morphological type. Large circles represent the averaged relation in mass intervals of 0.25 dex for each color-coded morphological type.
