Accuracy of the true-z estimation characterized by ${\displaystyle \sum _{ij\prime }}|{\widehat{P}}_{ij\prime }-P_{ij\prime }^{\mathrm{true}}|$, is plotted as a function of α, which measures the relative importance between SC and CZ. The line and the associated color band represent the median and the 16 and 84 percentiles among 100 mocks. We have shown the results for three spec-z sample consisting of the most massive 5%, 1%, and 0.5% galaxies in the spec-z sample. The black dashed line indicates the fiducial value α = 1.
