Reconstructed gravitational potentials in a) three and b) two dimensions are plotted as functions of radius and compared with the true potentials. In each panel, the blue, light blue and sky blue points show the true potential determined from the convergence map, while the red, orange and yellow points show the result of our reconstruction method. The corresponding relative deviation as a function of radius assuming the z-axis as a line of sight is shown in Fig. 9.
