* \brief Class to describe tracker LEVEL2 data. |
| 234 |
* |
| 235 |
* A tracker events is defined by some general variables, plus the collection of all the fitted tracks and all |
| 236 |
* single clusters on X and Y views. |
| 237 |
* Tracks and single clusters ("singlets") are described by the classes TrkTrack and TrkSinglet respectivelly. |
| 238 |
* |
| 239 |
* Each track may have an "image", due to the ambiguity on the Y view, which is stored also. |
| 240 |
* Thus, the number of stored tracks ( ntrk() ) differs from the number of "physical" tracks ( GetNTracks() ). |
| 241 |
* Proper methods allow to sort tracks and select the physical ones ( GetTracks() ). |
| 242 |
* |
| 243 |
* The event status indicates the processing status of data from each DSP, according to the following |
| 244 |
* notation: |
| 245 |
* |
| 246 |
* xxxx xxxx xxxx xxxx xxxx xxxx |
| 247 |
* |||| |||| |||| |||| |||| ||||_ 0 missing packet |
| 248 |
* |||| |||| |||| |||| |||| |||__ 1 CRC error |
| 249 |
* |||| |||| |||| |||| |||| ||___ 2 on-line software alarm (latch-up, timeout ecc...) |
| 250 |
* |||| |||| |||| |||| |||| |____ 3 jump in the trigger counter |
| 251 |
* |||| |||| |||| |||| ||||______ 4 decode error |
| 252 |
* |||| |||| |||| |||| |||_______ 5 n.clusters > maximum number (level1 processing) |
| 253 |
* |||| |||| |||| |||| ||________ 6 |
| 254 |
* |||| |||| |||| |||| |_________ 7 |
| 255 |
* |||| |||| |||| ||||___________ 8 n.clusters > maximum value (level2 processing) |
| 256 |
* |||| |||| |||| |||____________ 9 n.couples per plane > maximum values (vector dimention) |
| 257 |
* |||| |||| |||| ||_____________ 10 n.doublets > maximum values |
| 258 |
* |||| |||| |||| |______________ 11 n.triplets > maximum values |
| 259 |
* |||| |||| ||||________________ 12 n.yz-clouds > maximum values |
| 260 |
* |||| |||| |||_________________ 13 n.xz-clouds > maximum values |
| 261 |
* |||| |||| ||__________________ 14 n.candidate-tracks > maximum values |
| 262 |
* |||| |||| |___________________ 15 n.couples per plane > maximum values (for Hough transform) |
| 263 |
* |||| ||||_____________________ 16 |
| 264 |
* |
| 265 |
* |
| 266 |
* For all data processed before June 2007 the event status was coded according to |
| 267 |
* a different rule: |
| 268 |
* |
| 269 |
* Status of level1 processing |
| 270 |
* 0 -- OK |
| 271 |
* 1 -- missing packet |
| 272 |
* 2 -- 1 CRC error |
| 273 |
* 3 -- 2 on-line software alarm (latch-up flags asserted or n.transmitted-words = 0) |
| 274 |
* 4 -- 3 jump in the trigger counter |
| 275 |
* 10 -- 4 decode error |
| 276 |
* 11 -- 5 n.clusters > maximum number (for level1 processing) |
| 277 |
* Status of level2 processing |
| 278 |
* 21 -- 0 n.clusters > maximum value (for level2 processing) |
| 279 |
* 22 -- 1 n.couples per plane > maximum values (vector dimention) |
| 280 |
* 23 -- 2 n.doublets > maximum values |
| 281 |
* 24 -- 3 n.triplets > maximum values |
