Function documentation

THaVDC(const char* name, const char* description = "", THaApparatus* a = 0)
 Constructor
THaAnalysisObject::EStatus Init(const TDatime& date)
 Initialize VDC. Calls standard Init(), then initializes subdetectors.
Int_t ReadDatabase(const TDatime& date)
 Read VDC database
~THaVDC()
 Destructor. Delete subdetectors.
Int_t ConstructTracks(TClonesArray* tracks = 0, Int_t flag = 0)
 Construct tracks from pairs of upper and lower UV tracks and add
 them to 'tracks'
void Clear(Option_t* opt = "")
 Clear event-by-event data
Int_t Decode(const THaEvData& )
 Decode data from VDC planes
Int_t CoarseTrack(TClonesArray& tracks)
Int_t FineTrack(TClonesArray& tracks)
 Calculate exact track position and angle using drift time information.
 Assumes that CoarseTrack has been called (ie - clusters are matched)
Int_t FindVertices(TClonesArray& tracks)
 Calculate the target location and momentum at the target.
 Assumes that CoarseTrack() and FineTrack() have both been called.
void CalcFocalPlaneCoords(THaTrack* track, const THaVDC::ECoordTypes mode)
 calculates focal plane coordinates from detector coordinates
void CalcTargetCoords(THaTrack* the_track, const THaVDC::ECoordTypes mode)
 calculates target coordinates from focal plane coordinates
void CalcMatrix(const double x, vector<THaMatrixElement>& matrix)
 calculates the values of the matrix elements for a given location
 by evaluating a polynomial in x of order it->order with
 coefficients given by it->poly
Double_t CalcTargetVar(const vector<THaMatrixElement>& matrix, const double powers[][5])
 calculates the value of a variable at the target
 the x-dependence is already in the matrix, so only 1-3 (or np) used
Double_t CalcTarget2FPLen(const vector<THaMatrixElement>& matrix, const Double_t powers[][5])
 calculates distance from the nominal target position (z=0)
 to the transport plane
void CorrectTimeOfFlight(TClonesArray& tracks)
void FindBadTracks(TClonesArray& tracks)
 Flag tracks that don't intercept S2 scintillator as bad
void Print(Option_t* opt) const
THaVDCUVPlane* GetUpper()
 Get and Set Functions
{ return fUpper; }
THaVDCUVPlane* GetLower()
{ return fLower; }
Double_t GetVDCAngle()
{ return fVDCAngle; }
Double_t GetSpacing()
{ return fUSpacing; }
Double_t DoPoly(const int n, const vector<double>& a, const double x)
Double_t PolyInv(const double x1, const double x2, const double xacc, const double y, const int norder, const vector<double>& a)
