Planck 2018 TE (top) and EE (bottom) power spectra. At multipoles ℓ ≥ 30 we show the coadded frequency spectra computed from the Plik cross-half-mission likelihood with foreground and other nuisance parameters fixed to a best fit assuming the base-ΛCDM cosmology. In the multipole range 2 ≤ ℓ ≤ 29, we plot the power spectra estimates from the SimAll likelihood (though only the EE spectrum is used in the baseline parameter analysis at ℓ ≤ 29). The best-fit base-ΛCDM theoretical spectrum fit to the Planck TT,TE,EE+lowE+lensing likelihood is plotted in light blue in the upper panels. Residuals with respect to this model are shown in the lower panels. The error bars show Gaussian ±1σ diagonal uncertainties including cosmic variance. Note that the vertical scale changes at ℓ = 30, where the horizontal axis switches from logarithmic to linear.
