Marginalised posterior distributions for an extended set of cosmological parameters covering the matter density parameter, Ω_m, the matter fluctuation amplitude parameter, σ₈, the structure growth parameter, S₈, the spectral index, n_s, the dimensionless Hubble parameter, h, the baryon feedback amplitude parameter, A_bary, the intrinsic alignment amplitude, A_IA, and the linear bias parameters for the low and high BOSS redshift bins, b₁. The KiDS-1000 cosmic shear results (pink), can be compared to the BOSS galaxy clustering results (blue), the combination of cosmic shear with BOSS and 2dFLenS galaxy-galaxy lensing (GGL, purple), and the full 3 × 2 pt analysis (red). The combination of cosmic shear with galaxy clustering (orange) is only distinguishable from the 3 × 2 pt result in the A_bary and A_IA panels. For parameters constrained by the CMB, we also include constraints from Planck Collaboration VI (2020, grey).
