Field Detail

neutrinoFactor

public static int neutrinoFactor

In order to save CPU time, we increase neutrino cross section by this factor. As long as the meanfree path is by far shorter than the propagation length (presumably 1km), this is equivallent to the case when one neutrino particle represents multiple neutrinos whose number is equal to this factor. You (or RunManager class) have to devide this factor later to compensate this "artificial" enhancement of the neutrino cross section.
