Member Function Documentation

Int_t StiKalmanTrackFitter::fit ( StiTrack stiTrack,
Int_t  fitDirection 

Fit given track with helicoical track model.


  1. The fit is performed along a direction (inside-out||outside-in) prescribed by the value of the track flag "FittingDirection".
  2. In practice, the iteration through track nodes proceeds from first-to-last or last-to-first whether "trackingDirection==fitDirection"
  3. Use track node methods to do the actual propagation.
  4. Node with no hits are allowed as the evaluation of the track chi2 and updates are performed only if nodes hold a hit.

Implements StiTrackFitter.
