Fig. 21


Residual maps of the Q and U Stokes parameters after iteration on a simulation of signal (CMB+Galactic emissions) plus low frequency noise (α = 1,fknee = 0.1). Maps are degraded at 27.5 arcmin (HEALPix nside = 128). Large-scale residuals are compatible with the orbital dipole leakage as shown in Fig. 13. Stripes are destriping residuals.
