Priors on cosmological and nuisance parameters.
| Parameter name | Symbol | Prior |
|---|---|---|
| Density fluctuation amp. | S8 | [0.1, 1.3] |
| Cold dark matter density | Ωch2 | [0.051, 0.255] |
| Baryonic matter density | Ωbh2 | [0.019, 0.026] |
| Hubble constant | h | [0.64, 0.82] |
| Spectral index | ns | [0.84, 1.1] |
| Intrinsic alignment amp. | AIA | [−6, 6] |
| Baryonic feedback amp. | Abary | [2,3.13] |
| Redshift displacement | δz | 𝒩(μ, Cz) |
Notes. The Ωbh2 prior, motivated by BBN constraints from Olive & Particle Data Group (2014), is a conservative (5σ) equivalent to combining BBN data when external data from SDSS is used, similar to what is shown in Cuceu et al. (2019). Here, 𝒩(μ, Cz) is a normal distribution with mean μ and covariance Cz as estimated by Hildebrandt et al. (2021).
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
