Function documentation

void Analyze()
 Compute goodness of match parameter between upper and lower point.
 Essentially, this is a measure of how closely the two local tracks
 point at each other.
void Associate(THaTrack* track)
 Mark upper and lower points as well as their clusters
 as belonging to the given track
chi2_t CalcChi2() const
 Calculate chi2 and number of data points for the associated track
 and clusters
Int_t Compare(const TObject* ) const
 Compare this object to another THaVDCPointPair.
 Used for sorting tracks.
Double_t CalcError(THaVDCPoint* lowerPoint, THaVDCPoint* upperPoint, Double_t spacing)
 Calculate projected positions of points in opposite planes, measure
 how far they differ from partner point intercept, and return the sum
 of the squares of the distances
Double_t GetProjectedDistance(THaVDCPoint* here, THaVDCPoint* there, Double_t spacing)
 Project 'here' to plane of 'there' and return square of distance between
 projected position and intercept of 'there'
THaTrack* GetTrack() const
 Return track associated with this pair
Bool_t HasUsedCluster() const
 Return true if any cluster underlying this point pair is also part of
 another point pair that has already been chosen for making a track.
 This ensures each cluster is only ever used in at most one final track.
void Print(Option_t* opt = "") const
 Print details about this point pair (for debugging)
void Use()
 Mark this point pair as used (i.e. chosen for making a track)
 This does the following:

 (a) upper and lower points are marked as each other's partners
 (b) the underlying four clusters are marked as associated with this pair
 (c) the global slope resulting from the coordinate pair is calculated
     and stored in the clusters associated with the points
 (d) This pair is marked as used
void Release()
 Mark this track pair as unused
THaVDCPointPair(THaVDCPoint* lp, THaVDCPoint* up, Double_t spacing)

Double_t GetError() const
{ return fError; }
THaVDCPoint* GetLower() const
{ return fLowerPoint; }
THaVDCPoint* GetUpper() const
{ return fUpperPoint; }
Double_t GetSpacing() const
{ return fSpacing; }
