CMB Estimation of Cosmological Parameters

Acurate, high resolution measurement of the CMB anisotropies provides a means to a precise estimate of many cosmological parameters and crucial tests of many cosmological models. The precision and importance of these parameters makes CMB observations central to cosmology and extragalactic astrophysics.
