Table B.2:

Observed survey band X-ray luminosity scaling relations for the full REXCESS sample. Each set of observables (L,A) is fitted with a power law relation of the form $h(z)^n L = C(A/A_0)^{\alpha }$, with A0=5 keV and $2 \times 10^{14}~M_{\odot}$ keV, and n= -1, -9/5 and -7/3 for T, $Y_{\rm X}$ and M, respectively. Results are given for the BCES (Y|X) and BCES orthogonal fitting methods (see Sect. 2.4). The intrinsic natural logarithmic scatter about the best fitting relation in the ln-ln plane is given in each case.

L1/T1: luminosity/temperature interior to R500; L2/T2: luminosity/temperature in the [0.15-1] R500 aperture; MY: total mass estimated from the $M_{500}{-}Y_{\rm X}$ relation of Arnaud et al. (2007). a Since M is derived from $Y_{\rm X}$, the values of the scatter in the L-M relation are identical to those for the $L{-}Y_{\rm X}$ relation; b relations corrected for Malmquist bias.
