class THaVDCChamber: public THaSubDetector


Representation of a VDC chamber, consisting of one U plane and one
V plane in close proximity. With the Hall A VDCs, the two planes of a
chamber share the same mechanical frame and gas system.

This particular implementation takes the U plane as the reference for
specifying coordinates. It was also written assuming that the U plane is
below the V plane (smaller z). It should work the other way around as
well but that configuration has not been tested. If in doubt, one can
always swap the meaning of "U" and "V" such that "U" always means the
first (bottom) plane.

Function documentation

THaVDCChamber(const char* name = "", const char* description = "", THaDetectorBase* parent = NULL)
 Destructor. Delete plane objects and point array.
THaDetectorBase::EStatus Init(const TDatime& date)
 Initialize the chamber class. Calls its own Init(), then initializes
 subdetectors, then calculates local geometry data.
PointCoords_t CalcDetCoords(const THaVDCCluster* u, const THaVDCCluster* v) const
 Convert U,V coordinates of the given uv cluster pair to the detector
 coordinate system of this chamber. Takes u as the reference plane.
Int_t MatchUVClusters()
 Match clusters in the U plane with cluster in the V plane by t0 and
 geometry. Fills fPoints with good pairs.
Int_t CalcPointCoords()
 Compute track info (x, y, theta, phi) for the all matched points.
 Uses TRANSPORT coordinates.
void Clear(Option_t* opt = "")
 Clear event-by-event data
Int_t Decode(const THaEvData& evData)
 Decode both wire planes
void FindClusters()
 Find clusters in U & V planes
void FitTracks()
 Fit data to recalculate cluster position
Int_t CoarseTrack()
 Coarse computation of tracks
Int_t FineTrack()
 High precision computation of tracks
