21     * -----------------------------------------------------
22     * cuts on cluster signal
23     * -----------------------------------------------------
24 pam-fi 1.3 c parameter (dedx_x_min=70.)
25     c parameter (dedx_y_min=50.)
26     parameter (dedx_x_min=0.)
27     parameter (dedx_y_min=0.)
28 mocchiut 1.1 * -----------------------------------------------------
29     * number of GOOD strips around MAXS
30     * (NB this cut has been removed in track fitting but
31     * not in calibration)
32 pam-fi 1.3 * now the cut is used to avoid charge correlation
33     * for clusters with bad strips
34 mocchiut 1.1 * -----------------------------------------------------
35     * parameter (ngoodstr=1)
36 pam-fi 1.3 * parameter (ngoodstr=2)
37 mocchiut 1.1 parameter (ngoodstr=2)
38    
39     * -----------------------------------------------------
40     * first cuts on the parameters determined with
41     * the hough transform, in order to exclude from the
42     * following analysis not physical dublets and triplets
43     * (out of the geometrical acceptance of the apparatus)
44     * -----------------------------------------------------

48     parameter (alfxz2_max=0.47) !tg theta-xz (25 deg)
49     * -----------------------------------------------------
50     * cut on the position of the circle center:
51     * center inside the spectrometer volume is not physical
52     * ==> THE TRIPLET IS REJECTED

64     parameter (Dalfaxz3=1.)
65     * -----------------------------------------------------
66     * Cut on normalized distances in parameter space.
67     * Doublets/triplets are recursively included in a cloud
68     * if the distance from any of the points already included
69     * is less than this cut.
