Description
Determines when the spacecraft crosses into or out of a region with a certain level of flux. The ParticleFluxTimes method uses the NASA AP-8 and AE-8 particle flux maps to calculate the omnidirectional flux of the specified particle type with the energy level specified by minimumEnergy. The AP/AE maps contain collected data of proton and electron fluxes in the Earth's radiation belt with energy ranges from 0.04 MeV to 7 MeV for electrons and from 0.1 MeV to 400 MeV for protons. See the help file for links to more detailed documentation on the AP/AE maps. The user has the option to specify epoch and longitude offsets to include in the flux calculation.
