Relative difference on fσ₈ with respect to the ‘no magnification’ case of Fig. 5. The results for the standard analysis and fixed s of Fig. 5 are shown in blue and green, and the results of a fixed s analysis are shown in purple. For this last analsyis, we implemented magnification in data under the weak-lensing limit, i.e. we used a weight equal to μ(1 + (5s − 2)κ) instead of μ^2.5s (see also Sect. 3.1.2).
