The ratio ${\mathcal{D}}_{\ell }^{\mathit{BB}}/{\mathcal{D}}_{\ell ,0}^{\mathit{BB}}$ compares the angular power spectra of the B-mode systematic (solid lines) and statistical (dashed lines) residuals after component separation in the case of a model with intra-pixel complexity (d10-A, d10-B, d10-C and d12) with those for their counterpart without intra-pixel complexity (d10 and MBB(d12)). Results are shown for the parametric FGBuster and blind NILC pipelines in the left and right panel, respectively. All angular power spectra are computed excluding the Galactic plane with the Planck HFI GAL70 mask which retains 70% of the sky.
