Recovery of bulge Sérsic indices, n_B, as a function of B/T and m_r,B+D,Sim, showing the ratio in the fitted versus simulated values (top panel) and the standard deviation (bottom panel). Symbol sizes indicate the deviation from an ideal value, i.e. 1. Open red symbols indicate average values of <1. Ideal fits would produce small symbols in both panels (small offset, small scatter). The n_B values cannot be well recovered in disk-dominated galaxies. Only bins with more than 20 objects are shown, to ensure reasonable number statistics in each bin.
