crflux 1.0.3

Numerical model of the cosmic ray flux at Earth

A. Fedynitch, J. Becker Tjus, and P. Desiati, Phys. Rev. D 86, 114024 (2012), where we compared the effects of different Cosmic Ray Flux models - therefore the name.

This code is now an integral dependency of the atmospheric neutrino and air-shower cascade research code MCEq Matrix Cascade Equation (MCEq), providing:

• numerical models/parameterizations of high energy cosmic ray fluxes,

• conversions from all-particle into all-nucleon flux,

• other convenience functions for semi-analytical atmospheric lepton flux calculations.

Performance was never a bottle-neck, thus it’s not the most numerically brilliant code to date. But it does the job!

If you find it too slow for your applications feel free to open an issue or send a pull request or just branch/fork and let me know.
