49     The EVENT block stores the global event flag GOOD2 and the event counter NEV2.
50    
51     The CPU block stores the event tag extracted from the physics-packet
52     CPU-header (PKT_TYPE, PKT_NUM, OBT) and a variable that relates each event to
53     the calibration parameters (WHICH_CALIB).
54     (If WHICH_CALIB=0 (missing calibration) then GOOD2=.FALSE.)
55    
56     The TRACKS block stores track information:
57     NTRK - number of identified tracks
58     XM(6,NTRK) - measured coordinates associated to the track
59     YM(6,NTRK) '
60     ZM(6,NTRK) '
61     RESX(6,NTRK) - spatial resolution associated to each coordinate
62     RESY(6,NTRK) '
63     AL(5,NTRK) - TRACK PARAMETERS: X0,Y0,sin(THETA0),PHI0,DEFLECTION
64     CHI2(NTRK) - reduced chi^2 of the track
65     XGOOD(6,NTRK) - flag indicating if a plane was included in the track fitting
66     YGOOD(6,NTRK) '
67     XV(6,NTRK) - calculated coordinates
68     YV(6,NTRK) '
69     ZV(6,NTRK) '
70     AXV(6,NTRK) - calculated angles
71     AYV(6,NTRK) '
72    
73     The SINGLETS block stores information about those clusters not associated with
74     any track:
75     NCLSX(6) - number of singlets in each plane
76     NCLSY(6) '
