Residual amplitudes A_res(ν), (dark markers) EE (red) and BB (blue) for f_sky = [80, 90, 97]%, are shown from left to right. A fit to the data EE accounting for the three components of the moment expansion modeling separately, is described in Eq. (20) and is shown as a dashed line. A cross-power spectra correlation between pair of frequencies: 100 × 143, 100 × 217 and 143 × 217 is shown in smaller and lightened markers.
