Marginalised 2D posterior distributions for 68% (darker) and 95% (lighter) C.I. in the Ω_m − σ₈ plane. Here we exhibit the pseudo-C_ℓ constraints (red) in comparison with band-powers results from Asgari et al. (2021) (orange). SDSS BAO and RSD (blue) and its combination with the KiDS-1000 pseudo-C_ℓ measurements (purple) have a completely different degeneracy than the Planck 2018 constraints from the TTTEEE-lowE combination (green). We also compare it with the 3 × 2pt analysis from Heymans et al. (2021) (black-dashed).
