Component-separated CMB maps at 80′ resolution. Columns show Stokes I, Q, and U, respectively, while rows show results derived with different component-separation methods. The Galactic plane region in the SMICA maps results from a pre-processing step (masking and diffusive inpainting of a narrow Galactic region in all frequency channels), while no masks are applied to the other maps. In this plot, monopoles and dipoles have been subtracted with parameters fitted outside a |b| < 30° mask.
