Effect of the polarization prior on EE and BB detector-set difference power spectra. For 100–217 GHz, the green, orange, and blue lines on the EE and BB plots are the same as in Fig. 40 but here we add a red line, showing the power spectra for an alternative version of the NPIPE detector-set maps that are computed without the polarization prior. There is no blue line at 70 GHz because there is no comparable detector-set split in PR3, and 353 GHz is not shown because it is always calibrated without the polarization prior.
