+  * the TrkLevel1 branch, if present); it calls F77 subroutines that
+  * read the level1 common and fill the minimization-routine common.
+  * Some clusters can be excluded or added by means of the methods:
+  *
+  * TrkTrack::ResetXGood(int ip)
+  * TrkTrack::ResetYGood(int ip)
+  * TrkTrack::SetXGood(int ip, int cid, int is)
+  * TrkTrack::SetYGood(int ip, int cid, int is)
+  *
+  * NB! The method TrkTrack::SetGood(int *xg, int *yg) set the plane-mask (0-1)
+  * for the minimization-routine common. It deletes the cluster information
+  * (at least for the moment...) thus cannot be applied before
+  * TrkTrack::EvaluateClusterPositions().
+  *
+  * Different p.f.a. can be applied by calling (once) the method:
