The Interpolation routines AAfrag provide a compilation of results of the QGSJET-II-04m model for the energy spectra of various secondary particles (photons, neutrinos, electrons, positrons, and antiprotons), calculated over a wide energy range and for different reactions: proton-proton, proton-nucleus, nucleus-proton, and nucleus-nucleus collisions. The used version of QGSJET-II-04m has been fine-tuned to recent experimental data from the LHCf, LHCb, and NA61 experiments, in order to improve the description of secondary production at low energies.

v202: extended energy range; bugs in the fortran version 201 corrected
