-If the cross-section is not in cm^2^/nucleon but instead cm^2^/CH (or any other molecule) you will have to scale the `fScaleFactor` by the number of available target nucleons. For CCQE, nu,,mu,, interactions only occur off neutrons, which we have 6 of in CH. But the total number of nucleons in CH is 13. So if an experiment reports cross-section in cm^2^/CH we need to do `fScaleFactor*=13./6.`.

+If instead an experiment measures a CC1pi^+^ cross-section in `cm^2^/CH`, we scale by a factor 13 because CC1pi^+^ happens on both neutrons and protons.
