One sigma posterior likelihoods on the power n, the matter density ΩM and the constant equation of state w (when applicable) for various flat models containing matter, with or without a cosmological constant, and a nonlinear matter Lagrangian.
| Model assumptions | n | ΩM | w |
|---|---|---|---|
| ΩΛ = 0, Matter | 0.04 ± 0.04 | 0.39 ± 0.08 | N/A |
| ΩΛ ≠ 0, |Q| ≤ 0.05 |  |

N/A |
| ΩΛ ≠ 0, |Q| ≤ 0.50 | Unconstrained |  |
N/A |
| ΩΛ = 0, w = const. | Unconstrained |  |

Notes. The specific assumptions for each case are described in the main text. The constraints come from the combination of the Pantheon supernova data and Hubble parameter measurements.
