18 /*! @brief The number of hits cut for the calorimeter.
19 * An event survives this selection if the number of hit planes in the calorimeter
20 * is greater than some value. To save computing time, the class
21 * assumes that the track is externally computed for each event and stored in
22 * CaloAxis objects; pointers to these objects are passed as arguments to the constructor.
23 * The Check method will then ignore the PamLevel2 *event and assume that the
24 * current content of the CaloAxis objects are relative to the current event.
25 * It is an user's task to ensure that these assumptions are fulfilled every time
26 * Check or ApplyCut are called.
27 *
28 * CUT DEPENDENCIES: CaloTrackCut for the existence of the track (it can also provide the CaloAxis objects).
