Transition frequency-integrated ratio-relation, color-coded by M_vir with frequency ranges of positive AQN contributions. The low-energy frequency range shows in which the thermal AQN emission dominates. Low cluster masses tend to reside on a tangent, slightly offset towards higher values. The high-energy frequency range shows in which the nonthermal AQN emission dominates. Only AQN emission, originating from the lowest M_vir shows an excess over the thermal gas emission in the high-energy regime. We removed one cluster from the plot where for numerical reasons we could not compute ν_T and the associated $\tilde{J}$ reliably.
