Perlmutter et al. 1997 data and results

Above: Hubble diagrams for the first seven high-redshift supernovae: (a) uncorrected , with low-redshift supernovae of Hamuy et al. (1995) for visual comparison; (b) after "correction" for width luminosity relation. The square points are not used in the analysis because they are corrected based on an extrapolation outside the range of light curve widths of low-redshift supernovae (see paper). Insets show the high-redshift supernovae on magnified scales. The solid curves in (a) and (b) are theoretical for (, ) = (0, 0) on top, (1, 0) in middle, and (2, 0) on bottom. The dotted curves, which are practically indistinguishable from the solid curves, are for the flat universe case, with (, ) = (0.5, 0.5) on top, (1, 0) in middle, and (1.5, -0.5) on bottom.

Above: Contour plots of the 68% (1 ), 90%, and 95% (2 ) confidence regions in the vs. plane, for the first seven high-redshift supernovae. The solid lines show the two special cases of a = 0 cosmology and a flat = 1 cosmology.
