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) ' |
| 77 |
