Pioneer 10 Trapped Radiation Detector (TRD) 1-Hour Count Rates

Included are four rates, C1 and C3 from the Cerenkov counter and M1L and M3L from the Minimum Ionizing Particle Counter. C1 corresponds to >480 MeV/n ions (typically 80% protons and 20% Z>1 nuclei).

C3 corresponds to >650 MeV/n ions (typically 30% protons and 70% Z>1 nuclei). M1L corresponds to >80 MeV/n ions (typically 90% protons and 10% Z>1 nuclei). M3L corresponds to 80-300 MeV protons (50%) and >80 MeV/n Z>1 nuclei (50%).
