TB & EB Power Spectra
The TB and EB power spectra are computed using a pseudo-Cl estimator for the region outside the P06 mask in P and outside the Kp2 mask in T. The combined foreground-cleaned Q and V band maps are used for P, and the combined foreground-cleaned V and W band maps are used for T. The P data are weighted by N-1 for l<16, and by Nobs for l>16. The T data are flat weighted.
The data are provided as a table containing the following three columns:
The diagonal elements provide an estimate of the error, but should not be used as exact error bars. The complete Fisher matrix should be used for that purpose.
