/*! @brief An action that fills a live time histogram. |
| 18 |
* |
| 19 |
* This action reads a rigidity binning from a file and fills a live time histogram (text and ROOT format). |
| 20 |
* The live time corresponding to each event will contribute to the bin corresponding to the cutoff rigidity |
| 21 |
* of the event, eg., the lowest bin whose lower limit is greater than the cutoff rigidity of the event times |
| 22 |
* a coefficient (threshold coefficient, see constructor). If threshold*cutoff is lower than the |
| 23 |
* lower limit of the rigidity axis, then the live time will be added to the "zero bin", eg., a special bin |
| 24 |
* ranging from 0 to the lower limit. This special bin will be saved in a separate file. |
