All systematic effects: mean shear two-point correlation function ξ₊ (black) and corresponding mean convergence two-point correlation function ξ_κE estimated from incomplete noisy shear fields. The convergence maps have been estimated using KS (blue) and KS+ (red). The convergence two-point correlations were estimated outside the mask. The shaded area represents the uncertainties on the mean estimated on 1000 deg². Lower panel: normalised difference between the two upper curves.
