/*! @brief Cutting a band dE/dx vs. Beta for Helium. |
| 16 |
|
|
* This cut discards events where TOF dE/dx vs. Beta are outside the helium "corridor". This corridor is currently |
| 17 |
|
|
* defined by: |
| 18 |
|
|
* |

* dE/dx > 1 / (p[0] * pow(beta, p[4]) + p[1]) + p[2] + p[3]*beta |
| 20 |

|
* dE/dx < 1 / (p[5] * pow((*beta), p[9]) + p[6]) + p[7] + p[8]*(*beta); |

* where p[i] are calibration parameters. Currently, they are available for each single layer; the beta used is the beta[12] corresponding |
| 23 |
|
|
* to the TOF standalone track or to the TRK physical track, depending on the value of the standAlone parameter of the constructor. The |
| 24 |
|
|
* cut parameters have been obtained using the standalone beta, but they have proven to be good also for beta from tracker, so a single |
| 25 |
|
|
* set of parameter will be used for both cases. |
| 26 |
|
|
* If the required combination of planes has no available calibration, the one for S21 will be used (but it probably won't work well...). |
| 27 |
|
|
* In particular, there's no currently available calibration for combinations of layers. |
