S (r) – T relations at 0.15r_500c, r_2500c and r_500c. The white circles represent redshift evolution scaled average entropy measurements, blue error bars represent statistical uncertainties of the averages, and the red error bars represent the overall error budget of the average measurements resulting from the statistical and systematic uncertainties (see Sect. 4 for the details of the accounted systematics). The best-fit power-law models to the data points are plotted as light green lines, and the uncertainties of the best-fit lines are shown with dark green shaded regions.
