Fig. 8.
Sérsic index vs. luminosity. Upper panel: we show the location of different samples of LSB galaxies and, as a reference, that of subsamples of early-type galaxies of Virgo and NGC 5044. LSB galaxies show a very narrow range of n values in comparison to those shown by typical early-type galaxies. Lower panel: only the LSB galaxy samples are shown, to allow for a more detailed display. In both panels, symbol code is as given in the top margin of the upper panel.
