Table 3.

Model parameters and their priors, adopted from Asgari et al. (2021).

Parameter Type Prior Duplicated Description
ωcdm Cosmological [0.051, 0.255] Reduced cold dark matter density parameter
S8 Cosmological [0.1, 1.3]
ωb Cosmological [0.019, 0.026] Reduced baryonic matter density parameter
ns Cosmological [0.84, 1.1] Spectral index of the primordial curvature power spectrum
h Cosmological [0.64, 0.82] Reduced Hubble parameter at present cosmic time
Ωm Derived Total matter density parameter
σ8 Derived Present-time amplitude of matter density fluctuations

AIA Nuisance [ − 6.0, 6.0] × Amplitude of intrinsic galaxy alignments
Abary Nuisance [2, 3.13] × The baryonic feedback on the matter power spectrum
δz Nuisance 𝒩(μ,C) × Shift of the mean of the KiDS redshift distributions

Ωk Fixed 0 × Curvature density parameter
Mncdm Fixed 0.06 eV/c2 × Total mass of massive neutrino species

Notes. The three sections correspond to cosmological, nuisance, and fixed parameters, respectively. The first column provides parameter names, with a brief description given in the fifth column. The second column lists whether parameters are sampled (distinguishing further between cosmological and nuisance parameters), fixed, or determined as a derived parameter from the posterior chain. The third column contains the fiducial parameter value (if fixed) or else the prior range, with the interval indicating the boundaries of a top-hat prior. The five shift parameters δz are correlated through their covariance matrix C and their means μ are set to the mean values of the shifts of the tomographic redshift distributions from Hildebrandt et al. (2021). The fourth column shows whether a parameter is duplicated in the geometry–growth split or shared between the two regimes.
