Emissivities of muon neutrinos and antineutrinos from the decay of pions (blue curves), muons (orange curves), and kaons (green curves) for L₀ = 10⁵⁰ erg s⁻¹. The dashed curves represent the obtained output if all losses of the parent particles are neglected, while the solid curves mark the results if all the losses discussed are considered. The left plots correspond to a_ep = 1 and the right plots to a_ep = 100.
