Mean deflection spectra reconstructed by applying the FS-inpainting method to the lensed maps. “Raw lensing” denotes the spectrum reconstructed directly from the maps. In blue, we show the effect of correcting for the (known) analytical terms N⁽¹⁾ and N⁽²⁾. In red, one subtracts the Monte Carlo correction obtained from the set of unlensed maps. The dashed line is the true input spectrum. All points are assigned an error bar corresponding to the sample variance of each map within our Monte Carlo set.
