genie::flux::GCylindTH1Flux Class Reference

A generic GENIE flux driver. Generates a 'cylindrical' neutrino beam along the input direction, with the input transverse radius and centered at the input position. The energies are generated from the input energy spectrum (TH1D). Multiple neutrino species can be generated (you will need to supply an energy spectrum for each). More...

Detailed Description

A generic GENIE flux driver. Generates a 'cylindrical' neutrino beam along the input direction, with the input transverse radius and centered at the input position. The energies are generated from the input energy spectrum (TH1D). Multiple neutrino species can be generated (you will need to supply an energy spectrum for each).
