HOD obtained for SDSS DR7 implementing background subtraction method for different limiting absolute magnitude (M_lim = −16.0,−17.0,−18.0,−19.0,−20.0 and −21.0 as indicated in each panel). We show in solid lines the total HOD while solid circles show the satellite distribution. Dotted lines correspond to the best linear fit of satellite distribution. Just for comparison, we included the occupation corresponding to the synthetic catalogue estimated in the previous section (gray lines). Error bars are computed using the standard jackknife procedure.
