Cosmological constraints in the Ω_m − σ₈ plane, with 68% and 95% confidence intervals, obtained considering angular power spectrum (green contours) and correlation function (purple contours). Our findings are compared to the cosmological constraints derived from Planck Collaboration VI (2020) (top left) and from the same KiDS-DR3 cluster catalogue (bottom left), in particular: the number counts and 3D correlation function analyses presented in Lesci et al. (2022a,b). Right: summary plot containing the 1D marginalised posteriors for the structure growth parameter, S​₈.
