Residual frequency power spectra after subtraction of the Plik TT+tauprior best-fit model. We clean Galactic dust from the spectra from using the best-fit solution of Plik TT, TE, EE+tauprior. The residuals are relative to the baseline HM power spectra (blue points, except for those that deviate by at least 2 or 3σ, which are shown in orange or red, respectively). The vertical dashed lines delimit the ℓ ranges retained in the likelihood. Upper: TE power spectra. Lower: EE power spectra.
