Constructor & Destructor Documentation

◆ EigenPoint()

EigenPoint::EigenPoint	(	int	numNus = `3`,
		double	e = `0`,
		NuPath	p = `NuPath(0, 0)`,
		bool	n = `false`
	)

Constructor.

Uses number of neutrinos to fix eigensystem size.

Parameters

numNus	- the number of neutrino flavours
e	- the neutrino energy
p	- the neutrino path
n	- nu-nubar flag
