2716 Energetic Particles: Precipitating
Scientific paper
Magnetospheric particle flux is a function of particle energy, magnetic field, McIlwain's parameter, pitch angle, latitude, longitude, and time. Pitch angle distribution functions, which are some exponent of the sine function of the pitch angle, do not indicate equal number of particles from equal intervals of pitch angles. As a result, the particle flux calculated from the ratio of the count rate to the product of the geometrical factor and the energy interval of the detector is incorrect in the sense that the calculated flux represents an isotropic flux in which the count rate is independent of the direction of incidence, and depends on the size of the solid angle of acceptance. This leads to wrong comparison of particles fluxes obtained from two different instruments. Inclusion of the detector response function in the definition of flux takes care of the anisotropy built in the flux formula. The quantity for the correct comparison comes out to be the ratio of the observed detector count rate to the product of the detector area, instrument response function, and the integral over the particle energy spectrum. It is possible to make the correct comparison of particle fluxes measured with different telescope geometries at different epochs
