Notes. The three sections correspond to cosmological, nuisance, and fixed parameters, respectively. The first column provides parameter names, with a brief description given in the fifth column. The second column lists whether parameters are sampled (distinguishing further between cosmological and nuisance parameters), fixed, or determined as a derived parameter from the posterior chain. The third column contains the fiducial parameter value (if fixed) or else the prior range, with the interval indicating the boundaries of a top-hat prior. The five shift parameters δz are correlated through their covariance matrix C and their means μ are set to the mean values of the shifts of the tomographic redshift distributions from Hildebrandt et al. (2021). The fourth column shows whether a parameter is duplicated in the geometry–growth split or shared between the two regimes.
