| 307 |
* A tracker events is defined by some general variables, plus the collection of all the fitted tracks and all |
| 308 |
* single clusters on X and Y views. |
| 309 |
* Tracks and single clusters ("singlets") are described by the classes TrkTrack and TrkSinglet respectivelly. |
| 310 |
* |
| 311 |
* Each track may have an "image", due to the ambiguity on the Y view, which is stored also. |
| 312 |
* Thus, the number of stored tracks ( ntrk() ) differs from the number of "physical" tracks ( GetNTracks() ). |
| 313 |
* Proper methods allow to sort tracks and select the physical ones ( GetTracks() ). |
| 314 |
* |
| 315 |
* The event status indicates the processing status of data from each DSP, according to the following |
| 316 |
* notation: |
| 317 |
* |
| 318 |
* LSB --> 0 missing packet |
| 319 |
* 1 CRC error |
| 320 |
* 2 on-line software alarm (latch-up, timeout ecc...) |
| 321 |
* 3 jump in the trigger counter |
| 322 |
* 4 decode error |
| 323 |
* 5 n.clusters > maximum number (level1 processing) |
| 324 |
* 6 |
| 325 |
* 7 |
| 326 |
* 8 n.clusters > maximum value (level2 processing) |
| 327 |
* 9 n.couples per plane > maximum values (vector dimention) |
| 328 |
* 10 n.doublets > maximum values |
| 329 |
* 11 n.triplets > maximum values |
| 330 |
* 12 n.yz-clouds > maximum values |
| 331 |
* 13 n.xz-clouds > maximum values |
| 332 |
* 14 n.candidate-tracks > maximum values |
| 333 |
* 15 n.couples per plane > maximum values (for Hough transform) |
| 334 |
* MSB --> 16 |
| 335 |
* |
| 336 |
* |
| 337 |
* For all data processed before June 2007 the event status was coded according to |
| 338 |
* a different rule: |
| 339 |
* |
| 340 |
* Status of level1 processing |
| 341 |
* 0 -- OK |
| 342 |
* 1 -- missing packet |
| 343 |
* 2 -- 1 CRC error |
| 344 |
* 3 -- 2 on-line software alarm (latch-up flags asserted or n.transmitted-words = 0) |
| 345 |
* 4 -- 3 jump in the trigger counter |
| 346 |
* 10 -- 4 decode error |
| 347 |
* 11 -- 5 n.clusters > maximum number (for level1 processing) |
| 348 |
* Status of level2 processing |
| 349 |
* 21 -- 0 n.clusters > maximum value (for level2 processing) |
| 350 |
* 22 -- 1 n.couples per plane > maximum values (vector dimention) |
| 351 |
* 23 -- 2 n.doublets > maximum values |
| 352 |
* 24 -- 3 n.triplets > maximum values |
| 353 |
* 25 -- 4 n.yz-clouds > maximum values |
| 354 |
* 26 -- 5 n.xz-clouds > maximum values |
