712     * TrkTrack::ResetXGood(int ip)
713     * TrkTrack::ResetYGood(int ip)
714     * TrkTrack::SetXGood(int ip, int cid, int is)

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().
