Top panel: Averaged tangential shear profiles extracted from 256 light-cone random realizations with redshift z_s = 1, for the different analyzed models. Bottom panel: Corresponding residual with respect to the profile measured in the ΛCDM scenario. Both the plots utilize the following color scheme: ΛCDM (black), fR4 (green), fR5 (blue), fR6 (red), and ΛCDM_0.15 eV (purple). The shaded regions with the same colors around the curves represent the associated uncertainties, computed via the corrected covariance matrix (see Eqs. (31) and (A.2)). These are not displayed in the top panel for visualization reasons.
