The PARametrized Simulation Engine for Cosmic rays is a Monte Carlo generator to produce UHECR mock data sets including effects from source distribution, energy loss and deflection in extragalactic and galactic fields. It is realized as a set of PXL modules with graphical steering with the Vispa GUI.
Instead of a full Monte Carlo approach, in which you would follow individual cosmic rays on their trajectory, it calculates the discrete density function of the probability to observe a cosmic ray with energy E from an direction using parametrizations for the deflection and energy loss. From this pdf it generates mock data sets either from a parametrization of an observed spectrum, or a template data set.
A detailed publication on PARSEC can be found on the [arXiv].
