Stellar mass content in central (red lines) and satellite galaxies (blue lines). Upper panel: ⟨M_⋆|M_halo⟩ as a function of the halo mass for galaxies inside the FVS (dotted lines) and all galaxies (solid lines). Bottom panel: ratio of M_⋆ for galaxies in the FVS and the overall population. Error bars are computed using the standard jackknife procedure. For the central and satellite galaxies, M_halo corresponds to the M_200c of the main halo of the group.
