Public Attributes
double	chi2Track = 0
	Chi2 of track.
BoundTrackParameters	fittedParams
	Fitted perigee.
bool	isLinearized = false
	Is already linearized.
LinearizedTrack	linearizedState
	The linearized state of the track at vertex.
double	ndf = 0
	Number degrees of freedom Note: Can be different from integer value since annealing can result in effective non-interger values.
InputTrack	originalParams
	Original input parameters.
double	trackWeight = 1
	Weight of track in fit.
double	vertexCompatibility = 0
	Value of the compatibility of the track to the actual vertex, based on the estimation of the 3d distance between the track and the vertex.
