Dependence of the selection function with the luminosity function slope (bottom), core radius (middle), and cutoff radius (top). The values tested, from left to right, are α = −0.8, −0.95, and −1.1 for the luminosity function slope, r_core = 0.1, 0.15, and 0.2 h⁻¹ Mpc for the core radius, and r_max = 1.0, 1.5, and 2.0 h⁻¹ Mpc for the maximum radius. Richness classes are the same as shown in Fig. 6.
