Observed soft-band luminosity L_x as a function of the cluster mass M₅₀₀ (left panel) and redshift z (right panel). When showing the mass (redshift) trend in the left (right) panel, we re-normalize the observed quantity to the pivotal redshift z_Piv = 0.35 (mass M_piv = 1.4 × 10¹⁴h⁻¹M_⊙) as done in a similar manner in order to produce Fig. 10. The best-fit model and observed clusters are shown in the same way as in Fig. 10. The pink circles indicate the weighted mean of the eFEDS sample.
