Notes. Flux and luminosity errors include the Poisson errors and a 5% systematic error in the background estimation. Errors of parameters obtained from scaling relations include the measurement errors of the luminosity and temperature, respectively, and the intrinsic scatter of the scaling relations. We assume self-similar evolution for all the scaling relations and no evolution of their intrinsic scatters (see Sect. 2.2.1). (a) X-ray coordinates based on a maximum-likelihood fit of a PSF-folded beta model to the surface brightness distribution; (b) High et al. (2010); (c) spectroscopic temperature (Sect. 2.2.1), error bars averaged, assuming isothermality; (d) M-T relation from Arnaud et al. (2005), using relations for T >3.5 keV, self-similar evolution, radii calculated analytically from the mass estimates; (e)  $M_{500}{-}Y_{{\rm X}}$ relation (Arnaud et al. 2007). (f) L-T relation from Pratt et al. (2009), self-similar evolution, relation for the 0.5-2 keV luminosity, BCES orthogonal fit; (g)  $L{-}Y_{{\rm X}}$ relation from Pratt et al. (2009), self-similar evolution, relation for the 0.5-2 keV luminosity, BCES orthogonal fit. YX, the X-ray analogue to the Comptonization parameter Y, is the product of the gas mass and temperature (e.g. Kravtsov et al. 2006).
