|
* Method to calculate Beta from the 12 single measurements |
911 |
|
* we check the individual weights for artificial TDC values, then calculate |
912 |
|
* am mean beta for the first time. In a second step we loop again through |
913 |
|
* the single measurements, checking for the residual from the mean |
914 |
|
* The cut on the residual reject measurements > "x"-sigma. A chi2 value is |
915 |
|
* calculated, furthermore a "quality" value by adding the weights which |
916 |
|
* are finally used. If all measurements are taken, "quality" will be = 22.47. |
917 |
|
* A chi2 cut around 3-4 and a quality-cut > 20 is needed for clean beta |
918 |
|
* measurements like antiprotons etc. |
919 |
|
* The Level2 output is derived in the fortran routines using: 10.,10.,20. |
920 |
|
* @param notrack Track Number |

* @param cut on residual: difference between single measurement and mean |
