Mean per-halo numbers of simulated galaxies (top) and observed galaxies (bottom) as function of halo mass. Red crosses (blue points) indicate the true HOD of simulated red (blue) galaxies, where the error bars are the standard deviation of the mean over the 64 line-of-sights. The lines indicate the per-halo numbers inferred from the fit to the G3L signal for red (solid red) and blue galaxies (dashed blue). The shaded areas are the 68% credibility areas of the halo model fit. (a) MS. (b) KV450 × GAMA.
