Python I, II, and III CMB Anisotropy Measurement Constraints on Open and Flat-$\Lambda$ CDM Cosmogonies
We use Python I, II, and III cosmic microwave background anisotropy data to constrain cosmogonies. We account for the Python beamwidth and calibration uncertainties. We consider open and spatially-flat-Lambda cold dark matter cosmogonies, with nonrelativistic-mass density parameter Omega_0 in the ra...
