CDM density ωc [0.051, 0.255]
Density fluctuation amp. S8 [0.1, 1.3]
Scalar spectral index ns [0.84, 1.1]

Linear galaxy bias b1 [2] [0.5, 9]
Quadratic galaxy bias b2 [2] [−4, 8]
Non-local galaxy bias  [2] [−8, 8]
Virial velocity parameter avir [2] [0, 12]
Intrinsic alignment amp. AIA [−6, 6]
Baryon feedback amp. Abary [2, 3.13]

Redshift offsets δz 𝒩(μ; Cδz)

Notes. Primary cosmological parameters for the flat ΛCDM model are listed in the first section. The second section lists astrophysical nuisance parameters to model galaxy bias (with independent parameters for each of the two BOSS redshift bins as indicated with the bracket [2]), intrinsic galaxy alignments, and baryon feedback. Observational redshift nuisance parameters are listed in the final section. Prior values in square brackets are the limits of the adopted uniform top-hat priors. 𝒩(μ; C) corresponds to a five dimensional multivariate Gaussian prior with mean, μ, and covariance, Cδz.
