Fraction of galaxies for which z_spec is inside the highest probability density confidence interval (HPDCI) as a function of the confidence level c, computed separately for the colour-coded magnitude bins i = {17.5–18.5, 18.5–19.5, 19.5–20.5, 20.5–21, 21–21.5, 21.5–22, 22–22.5}. The left, middle, and right panels show results for the PDZs from HSC-SSP, J-PAS, and their conflation, respectively. Values above (below) the diagonal line indicate under-(over-)confidence in the PDZs.
