701   * Tracking method. It calls F77 mini routine.   * \brief Method to re-evaluate coordinates of clusters associated with a track.
702     *
703     * The method can be applied only after recovering level1 information
704     * (either by reprocessing single events from level0 or from  
705     * the TrkLevel1 branch, if present); it calls F77 subroutines that
706     * read the level1 common and fill the minimization-routine common.
707     * Some clusters can be excluded or added by means of the methods:
708     *
709     * TrkTrack::ResetXGood(int ip)
710     * TrkTrack::ResetYGood(int ip)
711     * TrkTrack::SetXGood(int ip, int cid, int is)
712     * TrkTrack::SetYGood(int ip, int cid, int is)
713     *
714     * NB! The method TrkTrack::SetGood(int *xg, int *yg) set the plane-mask (0-1)
715     * for the minimization-routine common. It deletes the cluster information
716     * (at least for the moment...) thus cannot be applied before
717     * TrkTrack::EvaluateClusterPositions().  
718     *
719     * Different p.f.a. can be applied by calling (once) the method:
720     *
721     * TrkParams::SetPFA(0); //Set ETA p.f.a.
722     *
