Notes.^(∗) Error-weighted average of the redshift evolution scaled entropy measurements of the grouped sample in units of keV cm² within the corresponding temperature bin. The first set of errors above and below the measurements represent the statistical uncertainty, and the errors presented within the parenthesis represent the systematic uncertainty (see Sect. 4 for the details of the accounted systematics).(^†) $S^{'} (r) = \frac{d \log (S (r))}{d \log (r / r_{500 c})}$ ${S^\prime }(r) = {{d\log (S(r))} \over {d\log \left( {r/{r_{500c}}} \right)}}$ , the slope of the error-weighted average entropy measurements as a function of dimensionless radius in logarithmic space, in units of log(keV cm²).
