The TE and TB, EE, and BB power spectra are computed using a pseudo-C_l estimator for the region outside the nine year polarization mask in P and outside the analysis 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.

Unbinned TE and TB, EE, and BB power spectra are provided as a tables containing the following columns:

the multipole moment l
the power spectrum in units of μK²
the error derived from the diagonal elements of the covariance matrix in units of μK²
the portion of column 3 attributed to measurement errors
the portion of column 3 attributed to cosmic variance, assuming the best-fit ΛCDM model.

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.

Binned versions of the TE and TB power spectra is also available in separate ASCII files with the following columns:

the mean multipole moment l
the smallest l contributing to the bin
the largest l contributing to the bin
the power spectrum in units of μK²
the error for the binned value, computed from the diagonal elements of the covariance matrix in units of μK²
the portion of column 5 attributed to measurement errors in units of μK²
the portion of column 5 attributed to cosmic variance in units of μK², assuming the best-fit ΛCDM model.
