Function documentation
Bool_t Fit(const TArrayI* volIdx, const TArrayI* volIdsFit = 0x0, AliGeomManager::ELayerID layerRangeMin = AliGeomManager::kFirstLayer, AliGeomManager::ELayerID layerRangeMax = AliGeomManager::kLastLayer)
Fit the track points. The method takes as an input the set of id's (volids) of the volumes in which one wants to calculate the residuals. The following parameters are used to define the range of volumes to be used in the fitting As a result two AliTrackPointArray's obects are filled. The first one contains the space points with volume id's from volids list. The second array of points represents the track extrapolations corresponding to the space points in the first array. The two arrays can be used to find the residuals in the volids and consequently construct a chi2 function to be minimized during the alignment procedures. For the moment the track extrapolation is taken at the space-point reference plane. The reference plane is found using the covariance matrix of the point (assuming sigma(x)=0 at the reference coordinate system.
void AddPoint(Float_t x, Float_t y, Float_t z, Float_t sy, Float_t sz)
Straight track fitter The method add a point to the sums used to extract track parameters
Bool_t GetPCA(const AliTrackPoint& p, AliTrackPoint& p2) const
Get the closest to a given spacepoint track trajectory point Look for details in the description of the Fit() method
