16    /*! @brief The geometric cut using the calorimeter track AND checking the TRK crossed sensor along Y.
17     *
18     * This cut checks if the track obtained from the calorimeter (with different methods) is inside the
19     * fiducial acceptance and if the TRK crossed sensor along Y for each of the 6 TRK planes is ySens
20     * (0 or 1, for increasing Y).
21     * The current 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).

36       *
37       * The CaloAxis arguments are pointers to objects which contain the calorimeter
38       * track information for current event.
39       *
40       * @param cutName The cut's name.
41       * @param xCaloAxis The pointer to the CaloAxis object for X axis.
42       * @param yCaloAxis The pointer to the CaloAxis object for Y axis.
43       * @param iMethod index of the method used to track: 0 means straight line;
44       *                1 means curved line (taking into account magnetic field and beta
45       *                from TOF stand-alone [assuming proton mass] with 3 parameters specified
46       *                below) starting from the top of the calorimeter and going backward
47       *                (straight line inside the calorimeter).
48       * Various combinations of TOF beta quality parameters are possible: default, low-quality beta (used for beta[12]): 10.,10.,20.; medium-quality beta: 5.,15.,4; high-quality beta: 3.,20.,3.
49       * @param ySens The TRK sensor identifier along Y (0 or 1 for increasing Y).
50       * @param xTolCaloTrack The tolerance for X view which defines the fiducial acceptance.
51       * @param yTolCaloTrack The tolerance for Y view which defines the fiducial acceptance.
52       * @param mass The particle's mass (used only when iMethod = 1). Default is #H_MASS.
53       * @param resMax Default: 10. (equivalent to beta[12])
54       * @param qualCut Default: 10. (equivalent to beta[12])
55       * @param chi2Cut Default: 20. (equivalent to beta[12])
