Posterior density distributions of the fitted log M₂₀₀. Each row shows the distributions for the pairs selected from the BCNz2 and DEEPz methods in purple and orange, respectively. The selection cuts according to pair properties are shown using thicker and narrower lines as referred to in the legends. Vertical lines indicate the median values and the shaded regions enclose 68% of the distributions corresponding to the errors. In each panel, the stacked pair sub-sample described in Table 3 is specified.
