Comparisons with literature data. Left panel: black symbols show z> 0.35 clusters from Mahdavi et al. (2013), whose best-fit using Eq. (5) is shown by the dot-dashed line. The cluster CL 1524+0957 is indicated by a diamond symbol. Coloured symbols and the dashed line show the “default” – relation for c_B13 as in the lower panel of Fig. 1. Middle panel: the same, but comparing to Foëx et al. (2012) (black symbols and dot-dashed line for best fit). X-ray masses are measured within . CL 1003+3253 and CL 1120+4318 are emphasised by special symbols. Right panel: scaling of lensing masses with the Y_X proxy. Black symbols show the z> 0.35 clusters from M13, to which the thick, dash-dotted line is the best fit. Shaded regions indicate the uncertainties to this fit. The thin, dash-dotted line gives the best fit M13 quote for their complete sample, while the thin solid and long-dashed lines mark the M₅₀₀–Y_X relations by V09a and Arnaud et al. (2010), respectively, for z = 0.40.
