Comparison between S₈ values for different surveys. All results are shown for both multivariate maximum posterior (MAP) and PJ-HPD (upper solid bar), as well as the marginal mode and the marginal S₈ credible interval (lower dot-dashed bar). The top three points show our fiducial KiDS-1000 results. The next four show a selection of recent cosmic shear analyses from external data as well as previous KiDS data releases. We note that S₈ does not fully capture the degeneracy direction for all of the analysis above (see the discussion in Sect. 4.1 and Appendix A). For example for the HSC-Y1 contours α = 0.45 was found to be the best fitting power. The last entry shows the Planck 2018 (TT, TE, EE+lowE) constraints. An extended version of this plot can be found in Appendix A.
