Same as Fig. 61, except showing only the lowest multipoles. Corrections for the low-ℓ NPIPE transfer function have been applied to both sets. Note that neither of the spectra has been corrected for potential biases from correlations arising due to joint processing of the two data splits. As shown in Planck Collaboration III (2020) and Planck Collaboration XI (2019), these correlations are significant for the 2018 half-mission data split, and reproducible in end-to-end simulations.
