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. | |
17 | // | |
