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. The first set of parameters uses the self-similar L − T and L − M relations from Pratt et al. (2009) for the bolometric luminosity. The second set of parameters (the no-evolution case) follows the prescription of Fassbender et al. (2011a) by removing one E(z) factor from the bolometric luminosity scaling relations of Pratt et al. (2009). In both scenarios, scaling relations are obtained by the BCES orthogonal fit algorithm (Akritas & Bershady 1996) and the input luminosities include the core regions. Parameters for XMMU J1532.2-0836 are upper limits. See Sect. 3.1 for more discussion.
