Table 2.
One-sigma (68.3% confidence level) constraints on the dark energy equation of state parameters wi, w0 and Δ (marginalised over the others), for the three-parameter dark energy L model described in the text, with a uniform prior on wi or on log10(1 + wi).
| Parameter | wi = 0 | Flat prior | Log prior |
|---|---|---|---|
| Δ | >0.37 | >0.34 | Unconstrained |
| log10(1 + w0) | <−2.29 | <−2.26 | <−1.97 |
| wi | N/A | <−0.99 | – |
| log10(1 + wi) | N/A | – | <−2.12 |
Notes. For comparison the one-sigma constraints on w0 and Δ for the two-parameter L model with wi = 0 discussed in Sect. 3 are also listed.
