Projected number density profiles, N(R), for all the considered subsamples of galaxy populations after stacking. In the left panel, we show the N(R) of the main galaxy populations (all red galaxies, all blue galaxies, etc), as well as the N(R) of the whole sample of selected cluster members. In the right panel, we show the four subcategories of the main populations (red with high M_*, blue with low M_*, etc)
