Polarization Power Spectra (includes binned versions)
Mission
WMAP
Description The TE, TB, EE, and BB power spectra are computed using a pseudo-C Unbinned TE, TB, EE, and BB power spectra are provided as tables containing the following columns: - the multipole moment l
- the power spectrum in units of μK
^{2} - the error derived from the diagonal elements of the covariance matrix in units of μK
^{2} - 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, TB, EE, and BB power spectra are 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 μK
^{2} - the error for the binned value, computed from the diagonal elements of the covariance matrix in units of μK
^{2} - the portion of column 5 attributed to measurement errors in units of μK
^{2} - the portion of column 5 attributed to cosmic variance in units of μK
^{2}, assuming the best-fit ΛCDM model.
The EE and BB spectra bins are noise-weighted averages; the TE and TB
spectra bins are straight averages. The binned cross spectra (TE and TB) are given in the form Also available are the BB power spectra before coadding frequences (Q, V, and W bands) as a table containing the following columns: - the multipole moment
- the Q band power spectrum, in units of μK
^{2} - the Q band error derived from the diagonal elements of the covariance matrix attributed to
measurement errors, in units of μK
^{2} - the V band power spectrum, in units of μK
^{2} - the V band error derived from the diagonal elements of the covariance matrix attributed to
measurement errors, in units of μK
^{2} - the W band power spectrum, in units of μK
^{2} - the W band error derived from the diagonal elements of the covariance matrix attributed to
measurement errors, in units of μK
^{2}
