Average bulge Sérsic indices, nB, as a function of B/T and mr,B+T,sim. Open red symbols indicate an average value of nB < 2 to distinguish bulges with low Sérsic indices (red, open) from bulges with high Sérsic indices (green, filled), i.e. ‘pseudo’ from ‘classical’ bulges. As bulges have a simulated distribution of nB around a value of 4, ideal fits would produce equally sized green boxes at all positions in this plot. In disk-dominated galaxies, a median value around nB ~ 1 is recovered, confirming that in this regime bulges more likely recover light from the disk. Only bins with more than 20 objects are shown, to ensure reasonable number statistics in each bin.
