OVRO CMB anisotropy measurement constraints on flat - ^ and open CDM cosmogonies

We use Owens Valley Radio Observatory (OVRO) cosmic microwave background (CMB) anisotropy data to constrain cosmological parameters. We account for the OVRO beamwidth and calibration uncertainties, as well as the uncertainty induced by the removal of non-CMB foreground contamination. We consider open and spatially-fiat-A cold dark matter cosmogonies, with nonrelativistic-mass density parameter Omega(0) in the range 0.1-1, baryonic-mass density parameter Omega(B) in the range (0.005-0.029)h(-2), and age of the universe to in the range (10-20) Gyr. Marginalizing over all parameters but Omega(0), the OVRO data favors an open (spatially-flat-Lambda) model with Omega(0) similar or equal to 0.33 (0.1). At the 2sigma confidence level model normalizations deduced from the OVRO data are mostly consistent with those deduced from the DMR, UCSB South Pole 1994, Python I-III, ARCO, MAX 4 and 5, White Dish, and SuZIE data sets.
