T E (top row) and TB (bottom row) cross-power spectra of the SRoll2 (blue curves) and FoCUS maps (red curves). The orange and black curves show the same results for the GNILC and Vansyngel maps. Each column corresponds to a different galactic mask. The cross-power spectra are binned in bins of width for T E and 0.2 for T B to reduce the noise variance. Dotted lines represent negative values.
