because in that redshift range the slope, the scatter, and the covariance matrix of the relations do not exhibit significant evolution. The mass$-Y_X$ relation continues to be the most suitable relation for this goal. Extending the analysis to the redshift range between 1 and 2 will be crucial to evaluate the impact generated by the AGN feedback.
