Stellar surface mass density profiles of the galaxies in our sample (gray lines), split into their different types according to their surface brightness profiles (see Sect. 2.2 for details). The profiles have been normalized in the radial direction to the location of their edges (according to Chamba et al. 2022). In each panel, the average profile is shown in magenta. The blue and green lines correspond to exponential fits to the weighted average profiles inside and outside R_edge. The spatial range used to fit the inner exponential is dictated by the excess of stellar mass produced by the bulge region.
