Mean completeness and purity along with associated errors as a function of galaxy magnitude (panel a)), projected separation, in r₂₀₀ units, of the galaxy from the cluster center (panel b)), halo mass (panel c)) and richness (panel d)), cluster redshift (panel e)), and cluster redshift accuracy σ_c/σ₀ (panel f)). Richness refers to cluster galaxies brighter than H_∗(z_p) + 1.5 and within r₂₀₀ radius of each halo. All values refer to σ₀ = 0.03 and a probability threshold P_thr = 20%.
