Probability of magnification for ψDM in the image plane. The probability was derived from the regions shown in Fig. 3 by counting the area (or pixels) with a given magnification. Each color corresponds to a different macromodel magnification, indicated by the thick vertical solid lines. The dotted and dashed lines correspond to the positive (POS) and negative (NEG) macromodel magnifications, respectively. The probability of magnification in the image plane is not representative of the observed magnification since it does not account for the multiplicity of images.
