Nflux	GENIE flux drivers
CGAstroFlux	A base class for the concrete astrophysical neutrino flux drivers
CNuGenerator
CNuPropagator
CGAtmoFlux	A base class for the FLUKA, BGLRS and ATMNC atmo. nu. flux drivers. The driver depends on data files provided by the atmospheric neutrino flux simulation authors in order to determine the angular and energy dependence for each neutrino species. The position of each flux neutrino [going towards a detector centered at (0,0,0)] is generated uniformly on a plane that is perpendicular to a sphere of radius Rl at the point that is determined by the generated neutrino direction (theta,phi). The size of the area of that plane, where flux neutrinos are generated, is determined by the transverse radius Rt. You can tweak Rl, Rt to match the size of your detector. Initially, neutrino coordinates are generated in a default detector coordinate system (Topocentric Horizontal Coordinate -THZ-): +z: Points towards the local zenith. +x: On same plane as local meridian, pointing south. +y: As needed to make a right-handed coordinate system. origin: detector centre Alternative user-defined topocentric systems can be defined by specifying the appropriate rotation from THZ. The driver allows minimum and maximum energy cuts. Also it provides the options to generate wither unweighted or weighted flux neutrinos (the latter giving smoother distributions at the tails)
