(particle='proton')[source]¶ Cosmic a cosmic ray spectral model at Earth.
These are the spectra assumed in this CTA study: Table 3 in https://ui.adsabs.harvard.edu/abs/2013APh….43..171B
The hadronic spectra are simple power-laws, the electron spectrum is the sum of a power law and a log-normal component to model the “Fermi shoulder”.
