Comparison of injection spectra of secondary particles computed using ATHEvA and LeHaMoC for the case of interactions of relativistic protons with a power-law photon field. From top left and in clockwise order: γ-ray spectra from neutral pion decay, pair spectra from charged pion decays, all-flavor neutrino spectra from charged pion decays, and pair spectra from the Bethe-Heitler process. The parameters used for this test can be found in Table 2 under the column Test 2.
