Effective radius (upper panel), mean surface brightness, and Sersic index (lower panel) obtained by GASPHOT for the WINGS galaxies in the V band as a function of the absolute magnitude for the four, broad morphological types. The mean values of the structural parameters are binned over the absolute magnitude. Ellipticals, S0s, early and late spirals are represented by circles, pentagons, squares, and triangles (red, green, cyan and blue).
