The background contribution depends on the energy spectrum of the incident particle population, being negligible for (differential) energy spectral slopes of -3.5 or steeper, increasing to 80% of the total counts for a slope of -1.0 or harder.

responds to protons in the energy range 9-19 MeV) is also sensitive to higher-energy particles which lose part of their energy in the telescope structure. As in the case of L1, the background contribution depends on the energy spectrum of the incident particle population, being negligible for (differential) energy spectral slopes of -2.0 or steeper, increasing to 80% of the total counts for a slope of +0.75 or harder.
