Redshift evolution of the catastrophic outlier fraction (f_c, upper panel), the bias (b, middle panel), and different estimates of the dispersions (σ, lower panel) as a function of spectroscopic redshift. The solid lines correspond to the full catalog, while the dashed lines correspond to the catalog once objects fainter than magnitude m_H = 23 are removed. Upper and lower values of the dispersion computed using percentiles with respect to the de-biased distributions are shown according to the legend. Left panel: distributions for the field plus cluster member galaxies and right panel: cluster member galaxies, i.e., those within haloes more massive than 10¹⁴ M_⊙.
