Steady state MW spectrum of photons resulting from monoenergetic proton injection with minimal cooling. Parameters are as in the previous figure. Full line is the synchrotron spectrum corresponding to the electrons injected from photopair (dotted line) and photopion (dot-dashed line) – see previous figure. Long dashed line is the proton synchrotron component while short dashed line are the γ-rays resulting from π⁰ decay.
