Loss rates for photohadronic interactions between protons and the photon fields of the companion star (blue), the accretion disc (green), the corona (orange), and local synchrotron emission in the jet (red). Dotted lines show the loss rate for the pair-creation channel and solid lines that of the photomeson channel. The total loss rate of the interaction (including pair-creation and photomeson channels) is plotted in solid purple line.
