Bayesian posteriors of the mass of the lens system for the planetary events KMT-2021-BLG-2010 and KMT-2022-BLG-1013. In each panel, the distributions drawn in red and blue represent the contributions of the bulge and disk lenses, respectively, and the distribution drawn in black is the sum of the contributions by the two lens populations. The solid vertical line indicates the median, and the dotted vertical lines represent 16% and 84% of the distribution.
