Function documentation
AliTrackPoint(Float_t x, Float_t y, Float_t z, const Float_t* cov, UShort_t volid, Float_t charge = 0, Float_t drifttime = 0, Float_t chargeratio = 0, Int_t clutype = 0)
Constructor
AliTrackPoint(const Float_t* xyz, const Float_t* cov, UShort_t volid, Float_t charge = 0, Float_t drifttime = 0, Float_t chargeratio = 0, Int_t clutype = 0)
Constructor
void SetXYZ(Float_t x, Float_t y, Float_t z, const Float_t* cov = 0)
Set XYZ coordinates and their cov matrix
Float_t GetResidual(const AliTrackPoint& p, Bool_t weighted = kFALSE) const
This method calculates the track to space-point residuals. The track interpolation is also stored as AliTrackPoint. Using the option 'weighted' one can calculate the residual either with or without taking into account the covariance matrix of the space-point and track interpolation. The second case the residual becomes a pull.
Bool_t GetPCA(const AliTrackPoint& p, AliTrackPoint& out) const
Get the intersection point between this point and the point "p" belongs to. The result is stored as a point 'out' return kFALSE in case of failure.
Float_t GetAngle() const
The method uses the covariance matrix of the space-point in order to extract the orientation of the detector plane. The rotation in XY plane only is calculated.
Bool_t GetRotMatrix(TGeoRotation& rot) const
Returns the orientation of the sensitive layer (using cluster covariance matrix). Assumes that cluster has errors only in the layer's plane. Return value is kTRUE in case of success.
AliTrackPoint& Rotate(Float_t alpha) const
Transform the space-point coordinates and covariance matrix from global to local (detector plane) coordinate system XY plane rotation only
AliTrackPoint& MasterToLocal() const
Transform the space-point coordinates and the covariance matrix from the (master) to the local (tracking) coordinate system
void SetAlignCovMatrix(const TMatrixDSym& alignparmtrx)
Add the uncertainty on the cluster position due to alignment (using the 6x6 AliAlignObj Cov. Matrix alignparmtrx) to the already present Cov. Matrix
AliTrackPoint& operator=(const AliTrackPoint& p)
