宇宙射线背景通量是在现有测量和理论的基础上模拟的，并在这里提出。该模型最初是为伽马射线大面积空间望远镜（GLAST）气球实验开发的，涵盖了整个立体角（4π sr），仪器的敏感能量范围（~10 MeV至100 GeV）和丰富的成分（质子，α粒子，e-，e+，μ-，μ+和伽马射线）。它表示在解析函数中，由于太阳活动和地球的地磁调制参数化。虽然该模型打算主要用于GLAST气球实验，但也介绍了低地球轨道的模型功能，可用于其他高能天体物理飞行任务。通过与GLAST气球实验数据的比较，验证了该模型的有效性。
Cosmic-ray background fluxes were modeled on the basis of existing measurements and theories and are presented here. The model, originally developed for the Gamma-Ray Large Area Space Telescope (GLAST) balloon experiment, covers the entire solid angle (4π sr), the sensitive energy range of the instrument (~10 MeV to 100 GeV), and the abundant components (proton, alpha particle, e-, e+, μ-, μ+, and gamma ray). It is expressed in analytic functions in which modulations due to solar activity and the Earth's geomagnetism are parameterized. Although the model is intended to be used primarily for the GLAST balloon experiment, model functions in low Earth orbit are also presented and can be used for other high-energy astrophysical missions. The model has been validated via comparison with the data of the GLAST balloon experiment.
