Low-multipole effective transfer functions for the pixel-based analysis. Due to the higher impact of noise on auto-QML compared to cross-spectra, we are not able to measure the effective transfer function at ℓ >  7 for 44 and 70 GHz, and at ℓ >  11 for 100 GHz. In the analysis the transfer function is conservatively enforced to be unity at ℓ  ≥  4 for 44 and 70 GHz, and at ℓ  ≥  7 for 100 GHz. Note that the transfer functions here are, as expected, different from those shown in Figs. 20 and 21. As emphasized in the text, the simulations used to calculate the transfer function must be processed using the same tools and approaches that are applied to the data. The pixel-based analysis here and the spectrum-based analysis represented in Figs. 20 and 21 are different.
