Fig. 6.| Upper panel: Averaged Hubble diagram with a linear redshift scale
for all supernovae from our low-extinction subsample. Here supernovae within

z < 0:01 of each other have been combined using a weighted average in order
to more clearly show the quality and behavior of the dataset. (Note that these
averaged points are for display only, and have not been used for any quantitative
analyses.) The solid curve overlaid on the data represents our best-t 
at-universe
model, (
M;
) = (0:25; 0:75) (Fit 3 of Table 8). Two other cosmological models
are shown for comparison: (
M;
) = (0:25; 0) and (
M;
) = (1; 0). Lower
panel: Residuals of the averaged data relative to an empty universe, illustrating the
strength with which dark energy has been detected. Also shown are the suite of
models from the upper panel, including a solid curve for our best-t 
at-universe
