Abstract

The general behaviour of the atmospheric γ-ray flux as a function of the residual atmosphere, zenith angle, and photon energy is approximated with simple analytical expressions. The free parameters are determined by comparison with the most recent models and the existing experimental measurements. The resulting formulae have an accuracy comparable to the mutual consistency of the available pieces of information, and at the same time are very convenient to use in numerical simulations.
