Table 1.
Free parameters considered in the analysis detailed in Sect. 4.1.
| Parameter | Description | Prior | Posterior |
|---|---|---|---|
| bSZ | Planck mass bias | [−2, 0.9] |
 |
| log Y* | Normalisation of the mass-observable relation | 𝒩(−0.19, 0.02) | – |
| α | Slope of the mass-observable relation | 𝒩(1.79, 0.08) | – |
| β | Redshift evolution of the mass-observable relation | 𝒩(0.66, 0.50) | – |
| σlnY | Intrinsic scatter of the mass-observable relation | 𝒩(0.173, 0.023) | – |
Notes. In the third column, the priors on the parameters are listed. In particular, a range between square brackets represents a uniform prior, and 𝒩(μ, σ) stands for a Gaussian prior with mean μ and standard deviation σ. In the fourth column, we show the median values of the 1D marginalised posteriors, along with the 16th and 84th percentiles. The posterior distributions of log Y*, α, β, and σlnY are not shown since these parameters are not constrained in our analysis.
