Upper panel: density maps from a M_V = −8.0 synthetic galaxy with observed in SECCO (Best case). The galaxy is located at six different distances from D = 0.5 Mpc to D = 2.5 Mpc. The density scale is in terms of σ over the background (see Paper I). Lower panel: CMD of stars within 1 R_h of the centre of the synthetic galaxies shown above. Stars from the synthetic population are plotted in grey while field stars are plotted in black.
