Parameters of HOD for satellite galaxies (see Eq. (4)). Top and bottom panels show M₀ and α parameters, respectively, as a function of the limiting magnitude. Our results are shown in grey circles while black circles correspond to results of Yang et al. (2008). There is a good agreement between both results, furthermore our method allows to extend the range of absolute magnitude to fainter values up to M_lim = −16.0 without losing statistical strength (shaded area). Parameters and error bars correspond to the best values obtained following the χ² minimization method.
