Outlier rate as a function of the odds parameter (symbols with error bars) and distribution of odds values (open histograms, scale on the right axis) for photo-z obtained with each of the photo-z codes used by HSC-SSP. Horizontal error bars represent the intervals in which η is calculated. Vertical error bars indicate 68% confidence intervals for η estimated with the Wilson (1927) formula for binomial distributions. The dotted diagonal line represents the expected relation between η and odds for realistic PDZs.
