Residuals of the reconstructed power spectrum of the lensing potential averaged over 300 full-sky lensed simulations in presence of the point sources mask. Top panel presents the gradient mode of the deflection (i.e. the lensing potential). Bottom panel presents the reconstructed curl modes. In both cases, we compare with the full-sky case (red for the gradient modes and green for the curl modes). Filled rectangles represent the theoretical dispersion expected for a single reconstruction.
