Ratio map expressed in $\tilde{J}$, shown in the left column. The thermal gas, AQN, and synchrotron emission of Coma integrated over 1.40 GHz to 4.85 GHz, projected 3 r_vir along the line of sight are given in the right column (from top to bottom). In this frequency window, the synchrotron emission of Coma is well constrained through radio emission (Thierbach et al. 2003). Due to the strong radio emission of Coma, here the contribution to the diffuse emission by AQNs is in the sub-percent level.
