Shown below is a likelihood plot of the 67%, 90%, 85% and 99% confidence regions on the dimensionless matter density and cosmological constant parameters, as determined for a flat Universe model from simulated data mimicking
- the 42 high-redshift supernovae of Perlmutter et al. (1999) combined with the MAXIMA CMBR constraints (larger set of contours)
- 1 year's worth of SNAP satellite observations of high redshift supernovae (smaller set of contours)
