Lens-model properties of each of the models shown in Fig. 7. The first row of each model shows the true values, while the second row shows the means and standard deviations of the measurements coming from a likelihood analysis, as described in Section 4. The parameters c_x and c_y are the x and y coordinates of the centroid of the main lens, and e_xe_y are the x and y component of the ellipticity of the main lens profile. The true θ_E and γ for the perturbers are not applicable because they follow NFW profiles instead of EPL profiles.
