Table 1: Physical cluster parameters. $M_{\rm 500}$ , $M_{\rm g, 500}$ and $f_{\rm g,500}$ are the total mass, gas mass and gas mass fraction respectively, within the radius R₅₀₀, inside which the mean mass density is 500 times the critical density at the cluster redshift. $T_{\rm X}$ is the spectroscopic temperature within [0.15-0.75]R₅₀₀ and $Y_{\rm X}= M_{\rm g, 500} T_{\rm X}$ . Values are given for a $\Lambda$ CDM cosmology with $\Omega _{\rm m}=0.3$ , $\Omega _{\Lambda }=0.7$ , H₀=70 km s^-1 Mpc^-1. Errors are $1~\sigma$ .
Table 2: Observed scaling relations. For each observable set (B,A), we fitted a power law relation of the form $B = C(A/A_0)^\alpha$ , with $A_0 = 5~{\rm keV}; 4\times10^{13}~M_{\odot}; 2\times10^{14}~M_{\odot}~\rm keV$ for $T_{\rm X}$ , $M_{\rm g, 500}$ and $Y_{\rm X}$ respectively. $\sigma _{\rm log,r}$ and $\sigma _{\rm log,i}$ are the raw and intrinsic scatter about the best fitting relation in the $\log$ - $\log$ plane. The M₅₀₀- $T_{\rm X}$ relation is the same as that given in Arnaud et al. (2005).
