The standard deviation of the analytical likelihood distribution of χ_a (which is given by the goodness-of-fit of the cosmic shear two-point statistic signal scaled by a factor of a) as a function of the factor a. Each of the panels shows the effect on the shear signal of a different combination of the five KiDS-1000 tomographic bins (S1 to S5). The blue dots represent the σ_χa values at ℓ = 70 which is just below the scale cuts applied in the anisotropic systematics model. The orange crosses are evaluated at ℓ = 100, while the green plus signs assume ℓ = 500, where the uncertainty is dominated by the shape noise. The panel in the upper right corner shows how the 1σ intervals of the likelihood marginals from KiDS-SBI vary with respect to the change in S₈ relative to $S_8^{\mathrm{fid}}=0.754$ as shown in Fig. 17. The grey dashed line in each panel shows a direct proportionality for reference.
