Mass maps obtained using different reconstruction techniques, from a specific tile of the simulated footprint. Upper left: True convergence map derived directly from the simulated κ field (after pixelising the per-object convergence). Upper right and lower left: Mass maps generated by the KS and iKS methods, respectively, both smoothed with a Gaussian kernel (standard deviation of 2 arcmin) for visualisation purposes. Lower right: MCALens mass map. The iKS method implements inpainting of the missing data, and the unmasked regions of the patch are outlined in white. Note that the white line outlines only the large unmasked areas, for better visualisation purposes.
