The solid curve overlaid on the data represents our best-fit flat-universe model, $(\Omega _M,\Omega _\Lambda = (0.25, 0.75)$. Two other cosmological models are shown for comparison. (Center): Our latest joint measurements of $\Omega _M$ and $w$ assuming $\Omega _M + \Omega _\Lambda = 1$ and that $w$ is not time-varying. Confidence regions (68\% and 90\%) are shown for the SCP SN Ia data overlaid with LSS measurements and combined CMB measurements. (Right): 68\% statistical confidence intervals on the dark energy equation of state possible from {\it SNLS} when it is completed 5 years from now, assuming a flat universe (from CMB measurements), and with (solid) and without (dotted) a prior on $\Omega _M$ from Large-Scale Structure. If a small systematic error is introduced, the statistical confidence interval will miss the correct simulated $\Lambda $ ($w=-1$) solution by $2\sigma $ (long-dash). }}{11}} \@writefile{lof}{\contentsline {figure}{\numberline {2}{\ignorespaces {\it Left:} I-band, B-band lightcurves and B-I color curve for a normal supernova.
