GAMERA
is a project launched by the Max Planck Insitute for Nuclear Physics in Heidelberg (MPIK), an open-source C++/python package which handles the spectral modelling of non-thermally emitting astrophysical sources in a simple and modular way. It allows the user to devise time-dependent models of leptonic and hadronic particle populations in a general astrophysical context (including SNRs, PWNs and AGNs) and to compute their subsequent photon emission.
GAMERA is written in C++ and can be wrapped to python as the GAMERA Python Package (GAPPA)
The software is listed in the Astrophysics Source Code Library

A new tutorial about the calculation of neutrino emission with the Radiation class has been added to the documentation. Take a look here.
Additionally, the documentary now has a page providing explanations of numerical subtleties and how to deal with them here.
