/*! @brief Track refitting. |
| 15 |
|
* |
| 16 |
|
* This action refits the TRK track using only level 2 data. This means that it will use the same |
| 17 |
|
* clusters which are associated to the track, with the possibility to mask or shift some of them. |
| 18 |
|
* If a refit fails the event will not be discarded (since this is not a cut) but chi2 will be negative, |
| 19 |
|
* and the event will be subsequently discarded by an eventual TrkPhSinCut. |
| 20 |
|
* This action can be used also before TrkPhSinCut, since it checks for the existence of at least |
| 21 |
|
* one track before refitting. The refitted track is always the first "physical" track; the ordering |
| 22 |
|
* criterion can be set using #SetSortingMethod. If, instead, this action is placed after a TrkPhsinCut |
| 23 |
|
* it is not necessary to set this parameter, since the value used for TrkPhSinCut will be automatically |
| 24 |
|
* used (of course, it can be used as well if a different ordering may be needed). |
| 25 |
|
* For a complete reprocess and fit use #ReprocessTrackAction. |
