Detailed Description

Interface class to call the different track algorithms for the Ftpc.

Definition at line 17 of file StFtpcTracker.hh.

Member Function Documentation

void StFtpcTracker::CalcEnergyLoss

(

)

Calculates dE/dx. This function replaces the old pams/ftpc/fde-module, but it is no longer used as everything happens in FitAnddEdxAndWrite().

Definition at line 387 of file StFtpcTracker.cc.

References Sorter().

Int_t StFtpcTracker::Fit

(

Bool_t

primary_fit

)

Fits tracks.

Definition at line 744 of file StFtpcTracker.cc.

void StFtpcTracker::Sorter	(	Double_t *	arr,
		Int_t *	index,
		Int_t	len
	)

Sorts hits in ascending order (depending on dE/dx). This function is needed to replace pams/ftpc/fde.
