Atmospheric neutrino energy distribution for high energy range looks wrong
I have tried to use Kamioka high energy flux files, which cover from 10 GeV to 10 TeV, to generate some neutrinos between 10 and 100 GeV.
The configuration is attached.
The resulting neutrino distribution for 50 events is also attached. The events are clustered in two intervals, 12.5 to 16 and 40 to 50 GeV.
It may be not a coincidence that two of the bins are 12.589 to 15.849 and 39.811 to 50.119 GeV.
The ROOT command used for producing (sort-of-)that plot is:
Events->Draw("simb::MCTruths_generator__GenieGen.obj.fMCNeutrino.fNu.E()>>HNuE(900, 10.0, 100.0)")
