695     * TrkTrack::ResetXGood(int ip)
696     * TrkTrack::ResetYGood(int ip)
697     * TrkTrack::SetXGood(int ip, int cid, int is)

701     * for the minimization-routine common. It deletes the cluster information
702     * (at least for the moment...) thus cannot be applied before
703     * TrkTrack::EvaluateClusterPositions().
