| 6 | // Class AliMUONGeometryDEIndexing |
| 7 | // ------------------------------- |
| 8 | // The class that provides conversion between the detection element Id |
| 9 | // and the index in the array. |
| 10 | // Used in storing DE transformations and segmentations. |
| 11 | // The detection elements numbering: |
| 12 | // DetElemId = chamberId*100 + [50] + detElemNum |
| 13 | // where chamberId = 1, 2, ..., 14 |
| 14 | // detElemNum = 0, 1, ... |
| 15 | // The number 50 is added to distinguish detector elements |
| 16 | // in the left and the right hemispheres. |
