TE Power Spectra (includes binned version)
The TE power spectrum is computed using a pseudo-Cl estimator for the region outside the P06 mask in P and outside the Kp2 mask in T. The foreground-cleaned V band with uniform weighting is used for T. The combined foreground-cleaned Q and V bands are used for P. Polarization weighting uses the full Ninv weighting for l ≤ 16 and Nobs weighting for l > 16.
The TE power spectrum 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.
A binned version of the TE power spectrum is also available in a separate file whose format and content are similar to those described above for the unbinned data. The choice of l bins is the same as that used in e.g., Figure 22 of Hinshaw et al. (see below).
