Log-scaled histograms of the wavelet peak counts as a function of the signal-to-noise ratio for the Kaiser-Squires (KS), iterative Kaiser-Squires (iKS), and MCALens methods, for the 25 simulated cosmologies. The four rows correspond to the three wavelet scales, [8, 16, 32] arcmin and the coarse map, and the columns correspond to the three mass-mapping methods. The histograms are colour coded by their S₈ value.
