Priors on the cosmological parameters used in this analysis when they are involved in the corresponding model.
| Parameter | Units | Description | Prior |
|---|---|---|---|
| Ωm | – | Mean matter density at present time | 𝒰(0.2, 0.95) |
| log As | – | Amplitude of the primordial power spectrum | 𝒰(–10, –8) |
| H0 |  |
Hubble expansion rate at present time | 𝒩 (67.77, 0.6) |
| Ωb | – | Mean baryon density at present time | 𝒰(0.046, 0.052) |
| ns | — | Spectra index of the primordial power spectrum | 𝒰(0.92, 1.0) |
| ∑mν | eV | Summed neutrino masses | 𝒰(0, 1) |
| log |fR0| | – | Logarithm of the derivative of f (R) with respect to the Ricci scalar taken at present-day | 𝒰(–8, –3) |
Notes. For the full set of priors used for the other parameters, including scaling relation and nuisance parameters, see Ghirardini et al. (2024). With 𝒰(min, max), we indicate a uniform distribution between “min” and “max”. With 𝒩(µ, σ), we indicate a normal distribution centered on µ and with the standard deviation, σ.
