Relative difference on fσ₈ with respect to its fiducial value as a function of redshift bins and sample configuration for ΛCDM particles. The data points in blue, green, and red refer to different analyses where we only account for RSD, add magnification bias with s fixed and s free, respectively (see also Sect. 3.2.3). The central values are those of the overall best fit, while error bars are those of the 68% confidence interval on the marginalised distribution. The dashed blue lines show the value for the unmagnified case. The grey shades highlight the ±5% and 10% ranges.
