704   * Tracking method. It calls F77 mini routine.   * \brief Method to re-evaluate coordinates of clusters associated with a track.
705     *
706     * The method can be applied only after recovering level1 information
707     * (either by reprocessing single events from level0 or from  
708     * the TrkLevel1 branch, if present); it calls F77 subroutines that
709     * read the level1 common and fill the minimization-routine common.
710     * Some clusters can be excluded or added by means of the methods:
711     *
712     * TrkTrack::ResetXGood(int ip)
713     * TrkTrack::ResetYGood(int ip)
714     * TrkTrack::SetXGood(int ip, int cid, int is)
715     * TrkTrack::SetYGood(int ip, int cid, int is)
716     *
717     * NB! The method TrkTrack::SetGood(int *xg, int *yg) set the plane-mask (0-1)
718     * for the minimization-routine common. It deletes the cluster information
719     * (at least for the moment...) thus cannot be applied before
720     * TrkTrack::EvaluateClusterPositions().  
721     *
722     * Different p.f.a. can be applied by calling (once) the method:
723     *
724     * TrkParams::SetPFA(0); //Set ETA p.f.a.
