SHAM predictions plotted with the fitted HOD model 1σ contour of the four- and five-parameter HOD fit results. In the top-left panel, the satellite fraction is fixed to 10%, and the σ parameter is varied. In the top-right panel, σ is fixed to 0.8, and the f_sat is varied. In the bottom-left (bottom-right) panel, shown as a function of σ and f_sat, is the distance between the HOD predicted by SHAM models and the five-parameter (four-parameter) HOD inferred from the observations. The dashed black line in the bottom-left panel corresponds to σ = 2 − f_sat/10. When compared to the five-parameter HOD fit, the bottom-left half, below the σ < 2 − f_sat/10 line of the parameter space, is preferred. Compared to the four-parameter HOD fit (bottom-right panel), the bottom-left half is also preferred. The dashed line represents σ = 2.4 − f_sat/10. The star identifies the lowest distance model. Empty circles identify the six lowest distance models.
