Left: the (gray points) vs. and (red points) vs. estimated from the stellar mass integrating the stellar mass surface density profiles. Gray and red dashed lines show the fits. Center: relation between and (dots) and (cross). color bar codes A_V at . Right: distribution of the ratio between half-mass and half-light ratio, corrected (gray bars) and un-corrected (black bars) by extinction. The dashed lines mark the averaged values of the distributions, log  / (std = 0.07) and log  / = −0.071 (std = 0.06).
