Notes. Centres are those of the fiducial cosmology, which includes the maximum likelihood points (not the 1D marginals) of our IA analysis. The “Informative” set of priors for photo-z bias parameters are approximations of constraints on equivalent parameters from the KiDS joint-probe analysis by van Uitert et al. (2018), with an extension for a fifth redshift bin.
