Model parameters and priors adopted in this analysis.
| Parameter | Description | Prior |
|---|---|---|
| Ωm | Mean matter density | [0.05, 0.6] |
| ln(1010As) | Amplitude of the primordial curvature perturbations | [0.0, 7.0] |
| σ8 | Amplitude of the matter power spectrum | – |
| Mmin [M⊙/h] | Minimum halo-mass to form a central galaxy | [10.0, 14.0] |
| M1 [M⊙/h] | Characteristic halo-mass to acquire one satellite galaxy | [10Mmin, 30Mmin] |
| α | Power-law index of the richness-mass relation | [0.1, 1.5] |
| σintr | Intrinsic scatter of the richness-mass relation | [0.1, 0.5] |
| s | Slope correction to the halo-mass function | 𝒩(0.037, 0.014) |
| q | Amplitude correction to the halo-mass function | 𝒩(1.008, 0.0019) |
| h | Hubble rate | 𝒩(0.7, 0.1) |
| Ωb h2 | Baryon density | 𝒩(0.02208, 0.0005) |
| Ων h2 | Energy density in massive neutrinos | [0.0006, 0.01] |
| ns | spectral index | [0.8, 1.2] |
Notes. The parameter σ8 has no prior interval, since it is a derived parameter. Ranges represent uniform flat priors, while 𝒩(μ, σ) stands for Gaussian priors.
