Class Description

 BrGeantToTpcTrackCandidate

 Module constructing a set of BrTpcTrackCandidates from
 BrGeantTracks and BrGeantHits in a TPC

 December 2001
 Mads Mikelsen


 Gave this class a new name; BrGeantToTpcTrackCandidate, this class
 was formerly known as BrGeantToDetectorTracks. This was done to
 mach the new track and tracking classes.

 Using module:

  t1_g2tpc_trackmaker = new BrGeantToTpcTrackCandidate("T1","T1 g2track");
  t1_g2tpc_trackmaker->SetDebugLevel(0);
  t1_g2tpc_trackmaker->SetMaxChisq(10.);
  t1_g2tpc_trackmaker->SetMinDedx(0.001); ... other settable parameters
  .....
  t1_g2tpc_trackmaker->Event(geant_node,geant_track_node);

BrGeantToTpcTrackCandidate() : BrModule()

BrGeantToTpcTrackCandidate(const Char_t* Name, const Char_t* Title) : BrModule(Name,Title)

~BrGeantToTpcTrackCandidate()

void Init()

This funktion must be called by user before event

void DefineHistograms()

 Define histograms.

void Clear()

void Print(Option_t* option) const

Bool_t CheckHit(BrGeantHit* hit)

 Check that geanmthit is inside dimensions found in
 DetectorParameters.txt
 Also check on energy?

BrTpcHit* GeantToTpcHit(BrGeantHit* hit)

Defines a BrTpcHit containing information held by a BrGeantHit

void Event(BrEventNode* InputNode, BrEventNode* OutputNode)

 Runs through all geant traks and findis the hits associated with
 each geant track. Then makes a Fit using these hits.
 Defines a new TpcTrackCandidate, with the geant track's UniqueID
 and the slopes obtained from tpctrackcandidate->Fit()
