Mean angular power spectra (over 200 simulations) of foregrounds (solid lines) and noise (dashed lines) residuals when PILC (green), ILC (blue) or NILC (red) are applied on B-mode data (reconstructed on the full-sky and then masked) of SWIPE+Planck (left) or SO (right) frequency maps. The spectra have been computed considering the 15% (for SWIPE) and 7.5% (for SO) of the sky which is expected to be less contaminated by Galactic emission in the CMB frequency channels of SWIPE and SO. The input foregrounds emission is simulated with the d1s1 sky model. A binning scheme of Δℓ = 10 is employed.
