Absolute difference between shear profiles with and without magnification of sources, for different local slopes α_s shown in the legend. The solid lines correspond to the first expression in Eq. (16) and dotted lines correspond to its approximation in the third line. The upper scale shows comoving transverse separation, and the redshifts are z_s = 0.99 for the sources and z_d = 0.41 for the lenses. The brown triangles with α_s = 1.75 and the orange ones α_s = 0.58 are directly comparable to the orange triangles in the upper panels of Fig. 2. We also show the goodness-of-fit parameter with 16 degrees of freedom for the solid line.
