We consider the shape of the likelihood and posterior surfac es to be used when fitting cosmological models to CMB temperature and polarisation po wer spectra measured from experiments. In the limit of an all-sky survey with Gaussian distributed pixel noise we show that the true combined likelihood of the four CMB power spect ra (TT, TE, EE & BB) has a… CONTINUE READING
