Spectra of neutrinos (solid lines) from pion decay (ν_μ and ﹩\overline{\nu _{\mu }}﹩) and muon decay (ν_e, ﹩\overline{\nu _{e}}﹩, ν_μ, and ﹩\overline{\nu _{\mu }}﹩) and synchrotron and IC photons emitted by pions (thin dashed lines) and muons (thick dashed lines) for ﹩R=10^{13}﹩ cm and ﹩l=10^{10}﹩ cm.
