2D marginal posterior distributions for the parameter pairs H₀–Ω_m (top) and σ₈–Ω_m (bottom) as computed with the BEYONDPLANCK-only likelihood (red); the BEYONDPLANCK likelihood extended with the Planck 2018 high-ℓ TT likelihood (green); the full Planck 2018 likelihood (yellow); the WMAP likelihood (blue); and, for the bottom figure, the joint cosmic shear and galaxy clustering likelihood from KiDS-1000 and BOSS (Heymans et al. 2021, gray).
