Python I, II, and III Cosmic Microwave Background Anisotropy Measurement Constraints on Open and Flat‐Λ Cold Dark Matter Cosmogonies

We use Python I, II, and III cosmic microwave background anisotropy data toconstrain cosmogonies. We account for the Python beamwidth and calibrationuncertainties. We consider open and spatially-flat-Lambda cold dark mattercosmogonies, with nonrelativistic-mass density parameter Omega_0 in the range0.1--1, baryonic-mass density parameter Omega_B in the range (0.005--0.029)h^{-2}, and age of the universe t_0 in the range (10--20) Gyr. Marginalizingover all parameters but Omega_0, the combined Python data favors an open(spatially-flat-Lambda) model with Omega_0 simeq 0.2 (0.1). At the 2 sigmaconfidence level model normalizations deduced from the combined Python data aremostly consistent with those drawn from the DMR, UCSB South Pole 1994, ARGO,MAX 4 and 5, White Dish, and SuZIE data sets.Comment: 20 pages, 7 figures, accepted by Ap
