16     /*! @brief The calorimeter track chi2 quality cut.
17     *
18     * This cut performs a check on chi2 of the calorimeter track. The current
19     * implementation uses the CaloAxis objects; to save computing time, the class
20     * assumes that the track is externally computed for each event and stored in
21     * CaloAxis objects; pointers to these objects are passed as arguments to the constructor.
22     * The Check method will then ignore the PamLevel2 *event and assume that the
23     * current content of the CaloAxis objects are relative to the current event.
24     * It is an user's task to ensure that these assumptions are fulfilled every time
25     * Check or ApplyCut are called.
26     *
27     * CUT DEPENDENCIES: CaloTrackCut for the existence of the track (it can also provide the CaloAxis objects).
