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-flat- \Lambda 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 t _ { 0 } 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 } \simeq 0.33 ( 0.1 ) .
At the 2 \sigma 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 , ARGO , MAX 4 and 5 , White Dish , and SuZIE data sets .
