Notes. The gas mass mg, the temperature t, and the luminosity l act as y1, y2, and y3, respectively. Y1 is an unbiased but scattered proxy of Z. Scatter data and correlations are meant as weighted averages over the redshift range. Values in square brackets are kept fixed in the regression. The last column lists the self-similar expectations. Quoted values are biweight estimators of the marginalised distributions.
