  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 ~= 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.
