Table 1: Best-fit results of the spectral and spatial analysis of the sample of galaxy clusters at redshift >0.4 and derived quantities at an overdensity corresponding to $\Delta _z=500$ in a Einstein-de Sitter universe. A Hubble constant of 70 km s^-1 Mpc^-1 in a flat universe with $\Omega _{\rm m}$ equals to 0.3 is assumed. Note: (i) RX J1347-1145 has a clear hot enhancement to the South-East of the main X-ray emission. A sector with position angle $90^{\circ }{-}180^{\circ }$ and centered on the X-ray peak has been masked in accordance with the analysis presented in Allen et al. (2002). (ii) In 3C 295, the central active galactic nucleus and regions of enhanced emission associated to the radio lobes have been masked (see Allen et al. 2001a). (iii) MS1054-0321 presents significant substructure (e.g. Jeltema et al. 2001). The temperature and the best-fit of the surface brightness profile are estimated from the main body of the cluster once a circular region centered at (RA, Dec; 2000) = $(10^{\rm h} 56^{\rm m} 55\hbox {$^{\prime \prime }$ }7,-3^{\circ } 37' 37'')$ and with radius of 36 arcsec is masked.
