17 pam-fi 1.1 *
18 pam-fi 1.2 * This cut checks if the track obtained from the calorimeter (with different methods) is inside the fiducial acceptance.
19 pam-fi 1.1 * The current 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).

34     *
35     * The CaloAxis arguments are pointers to objects which contain the calorimeter
36     * track information for current event.
37     *
38     * @param cutName The cut's name.
39     * @param xCaloAxis The pointer to the CaloAxis object for X axis.
40     * @param yCaloAxis The pointer to the CaloAxis object for Y axis.
41 pam-fi 1.2 * @param iMethod index of the method used to track: 0 means straight line;
42     * 1 means curved line (taking into account magnetic field and beta
43     * from TOF stand-alone [assuming proton mass] with 3 parameters specified
44     * below) starting from the top of the calorimeter and going backward
45     * (straight line inside the calorimeter).
46     * 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.
47 pam-fi 1.1 * @param xTolCaloTrack The tolerance for X view which defines the fiducial acceptance.
48     * @param yTolCaloTrack The tolerance for Y view which defines the fiducial acceptance.
49 pam-fi 1.2 * @param mass The particle's mass (used only when iMethod = 1). Default is #H_MASS.
50     * @param resMax Default: 10. (equivalent to beta[12])
51     * @param qualCut Default: 10. (equivalent to beta[12])
52     * @param chi2Cut Default: 20. (equivalent to beta[12])
