Energy densities of several photon fields: accretion disc (red solid line), BLR (blue solid line), DT (yellow solid line), CMB (black solid line), as a function of the distance from the central BH, computed with agnpy. The energy density of synchrotron radiation (green dotted line) and of the magnetic field (green dashed line) are plotted for comparison. The emitters parameters are specified in Table B.2. A BLR emitting the Lyα line is considered. The energy densities are expressed in the reference frame comoving with the second blob in Table B.1 (EC model).
