Histograms of debiased polarized intensity at 217 GHz (left) and 353 GHz (right) (Plaszczynski et al. 2014) of all (black), control (blue) and target1 (orange). (Dark) Gray shaded areas mark (68) 95 percent of the CMB contribution to the polarized intensity as inferred by smica for a FWHM beam of 30′ and for the footprint. The CMB contribution is negligible at 353 GHz but not at 217 GHz, especially for pixels of low . Histograms correspond to PR3 polarization maps with no CMB subtraction.
