Constraints on δ_z and the intrinsic alignment amplitude A_IA. The δ_z nuisance parameters represent our uncertainty in the mean of the redshift distributions. The input prior region is shown in grey. The prior for A_IA is flat within its boundaries (the full range is between −6 and 6), while correlated Gaussian priors are used for the δ_z nuisance parameters (the δ_z priors are shifted to have a zero mean). Results are shown for COSEBIs (orange), band powers (pink) and the 2PCFs (cyan).
