Marginalised cosmic shear constraints for the joint distribution of Ω_m and S₈ from KiDS-Legacy (yellow), DES-Y3 (green), and their combination (pink). These results can be compared to the CMB posterior inferred with the compressed Planck likelihood by Prince & Dunkley (2019). The black contour shows constraints from a joint analysis of KiDS-Legacy with DES Y3, DESI Y1 BAO, and Pantheon+ data. The inner and outer contours of the marginalised posteriors correspond to the 68% and 95% credible intervals, respectively.
