18 /*! @brief The calorimeter track chi2 quality cut.
19 *
20 * This cut performs a check on chi2 of the calorimeter track. The current
21 * implementation uses the CaloAxis objects; to save computing time, the class
22 * assumes that the track is externally computed for each event and stored in
23 * CaloAxis objects; pointers to these objects are passed as arguments to the constructor.
24 * The Check method will then ignore the PamLevel2 *event and assume that the
25 * current content of the CaloAxis objects are relative to the current event.
26 * It is an user's task to ensure that these assumptions are fulfilled every time
27 * Check or ApplyCut are called.
28 *
29 * CUT DEPENDENCIES: CaloTrackCut for the existence of the track (it can also provide the CaloAxis objects).
