Field border effects: third-order (upper panel) and fourth-order (lower panel) moments estimated on seven wavelet bands of the original convergence (black) compared to the moments estimated on the KS (blue) and KS+ (red) convergence maps reconstructed from noise-free shear maps. The shaded area represents the uncertainties on the mean estimated on 1000 deg². Lower panel: relative higher-order moment errors introduced by border effects.
