Scatter plots for the source and lens flux of the reconstruction depicted in Fig. 3. Top panel: pixel-wise comparison between the input source flux and its reconstruction. Bottom panel: similar pixel-wise comparison between the unconvolved lensed input source flux and its reconstruction. In both panels, the solid black line depicts the one-to-one correspondence between model and input flux. Furthermore, in the bottom panel, the dashed black lines depict the standard deviation of the noise σ_d.
