Impact on the shear profile as a function of α_d and z_d (Table 1c) for fixed flux limit of r = 22 mag, for a magnification of lens galaxies only. The redshift z_d is given on the (non-linear) top axis. Again, the effect switches its sign at α_d ≈ 1. It then rises up to 45% for larger α_d, while less impact is seen for α_d <  1. Different local slopes of the sources α_s at z_s = 0.99 leave the lens’ magnification unaffected.
