We have combined the type Ia supernova (SNe Ia) data from the High-z SN Search and the Supernova Cosmology Project, and binned the combined data by flux-averaging in redshift intervals of ∆z = 0.05 and ∆z = 0.1. We find that the unbinned data yield a Hubble constant of H0 = 65 ± 1 km s−1 Mpc−1 (statistical error only), a matter density fraction of Ωm = 0.7 ± 0.4, and a vacuum energy density fra...
