Pseudo-C_ℓ spectra of residuals for E and B modes (left and right columns, respectively) determined from the purified inpainting of the FFP10 simulations for all four component-separation methods. Solid curves show averaged spectra, with red corresponding to the residual masked with the reconstruction mask and blue corresponding to the residual masked with the confidence mask. Semi-transparent areas filled with grey show 68%, 95%, and minimum-to-maximum bounds for individual realizations.
