The Wilkinson Microwave Anisotropy Probe measured the temperature and polarization of the CMB over the full sky in the K, Ka, Q, V, and W microwave bands.

The WMAP produced this likelihood code, which takes in theory spectra for TT, EE, BB, and TE spectra and compares it to WMAP data.

The method used for the likelihood is different in different ell regimes and for different spectra.
