Comparison of the global properties of XLSSC 122 (blue point) with lower-z, SZ-selected clusters from SPT at redshifts 0.32 < z < 1.07 (gray points; Andersson et al. 2011). Luminosities are in the 0.5–2.0 keV rest-frame band. The SPT cluster temperatures are centre-excised (excluding radii <0.15 r₅₀₀), while the measurement for XLSSC 122 is not. Solid and dashed lines show the scaling relation constraints published by Andersson et al. (2011). Factors of E(z) = H(z)∕H₀ encode self-similar evolution of the scaling relations.
