Marginal posterior distributions for a selection of parameters that are significantly constrained by the data, including the derived parameters Ω_m and σ₈. Shown are one-dimensional marginals along the diagonal and two-dimensional marginal 1σ and 2σ credible regions elsewhere. Results are for the reference setup using a noiseless mock data vector of galaxy clustering (GC; red), cosmic shear (CS; green), and the combination of clustering and the weak lensing probes (‘3 × 2 pt’; blue). Input parameter values are indicated by the black dashed lines, which are excellently recovered by the MAP estimate (red crosses).
