Notes. For the base model, we do not quote constraints on h because this parameter is poorly constrained by cluster counts and the posterior distributions are driven by the hard prior. S8 is defined to be S8 ≡ σ8(Ωm/0.3)0.5. The last column indicates the priors used in this analysis. 𝒩(μ, σ2) corresponds to a Gaussian prior with mean μ and variance σ2 and 𝒰(A, B) a uniform prior within the range [A,B]. We do not quote constraints on the nuisance parameter used in the analysis.
