TransientVertex::TransientVertex

(

)

Empty constructor, produces invalid vertex

TransientVertex::TransientVertex	(	const GlobalPoint &	pos,
		const GlobalError &	posError,
		const std::vector< reco::TransientTrack > &	tracks,
		float	chi2
	)

Constructor defining the RecVertex by its 3D position and position uncertainty, its associated tracks and its chi-squared. The number of degrees of freedom is equal to 2*nb of tracks - 3.

Definition at line 18 of file TransientVertex.cc.

TransientVertex::TransientVertex	(	const GlobalPoint &	pos,
		const GlobalError &	posError,
		const std::vector< reco::TransientTrack > &	tracks,
		float	chi2,
		float	ndf
	)

Constructor defining the RecVertex by its 3D position and position uncertainty, its associated tracks, its chi-squared and its number of degrees of freedom. The ndf can be a float.

		float	chi2
	)

Constructor defining the RecVertex by the prior, the vertex 3D position and uncertainty, the associated tracks and the chi-squared. Since the prior brings information on 3 coordinates, the number of degrees of freedom is equal to 2*nb of tracks.
