Approximating the Likelihood Function of CMB Experiments
J. G. Bartlett, A. Blanchard, M. Douspis +1
We discuss the problem of constraining cosmological parameters with cosmic microwave background band--power estimates. Because these latter are variances, they do not have gaussian…

Constraints on Cosmological Parameters from Existing CMB Data
J. G. Bartlett, A. Blanchard, M. Le Dour +2
We use current cosmic microwave background data to constrain cosmological parameters. The results are presented as confidence regions in the (--) -- plane for both open and…
