◆ Init()

void PndGeanePro::Init ( FairTrackPar * TParam )

virtual

Method to initialize last track parameter of reconstructed track.

Position and momentum of particle at last point of track are copied to arrays that GEANE can use.

Reimplemented from PndPropagator.

◆ Propagate() [1/3]

Bool_t PndGeanePro::Propagate ( Int_t PDG )

Main propagate function that calls ERTRAK from GEANE to do the propagation.

Prior to calling this function, the GEANE must be set up properly. This is done by the Propagate(FairTrackPar*, FairTrackPar*) and Propagate(Float_t*, Float_t*, Float_t*, Float_t*, Int_t) functions.

Parameters

Int_t pdg code of the particle to propagate

Returns: kTRUE if propagation successfull

◆ Propagate() [2/3]

virtual Bool_t PndGeanePro::Propagate	(	FairTrackPar *	TStart,
		FairTrackPar *	TEnd,
		int	PDG
	)

virtual

Propagate function called by user.

Propagates track from start to end point and returns end point and momentum. Before calling Propagate, the destination of propagation must be set using

SetDestinationPlane,
SetDestinationVolume,
SetDestinationLenth,
SetDestinationPoint, or

SetDestinatioWire. In addition, the PCA propagation mode and direction must be set using SetPCAPropagation.

Parameters

TStart	start track parameters - usually the momentum and position at the last point of the reconstructed track
TEnd	the return track parameters at the end of propagation
PDG	the pdg code of the particle to propagate

◆ Propagate() [3/3]

virtual Bool_t PndGeanePro::Propagate	(	Float_t *	x1,
		Float_t *	p1,
		Float_t *	x2,
		Float_t *	p2,
		Int_t	PDG
	)

virtual

Propagate function called by user.

This propagate function takes in arrays with start position and momentum. Before calling this function, GEANE needs to be set up and the destination length needs to be set.

◆ SetBackProp()

inline

Method to set propagation to backwards propagation.
