506     * the TrkLevel1 branch, if present); it calls F77 subroutines that
507     * read the level1 common and fill the minimization-routine common.
508     * Some clusters can be excluded or added by means of the methods:
509     *
510     * TrkTrack::ResetXGood(int ip)
511     * TrkTrack::ResetYGood(int ip)
512     * TrkTrack::SetXGood(int ip, int cid, int is)

515     * NB! The method TrkTrack::SetGood(int *xg, int *yg) set the plane-mask (0-1)
516     * for the minimization-routine common. It deletes the cluster information
517     * (at least for the moment...) thus cannot be applied before
518     * TrkTrack::EvaluateClusterPositions().  
519     *
520     * Different p.f.a. can be applied by calling (once) the method:
521     *
