7 | // This is a class that makes SDigits out of Hits | |
8 | // A Summable Digits is the sum of all hits originating | |
9 | // from one in one tower of the EMCAL | |
10 | // A threshold for assignment of the primary to SDigit is applied | |
11 | // | |
12 | // SDigits need to hold the energy sum of the hits, but AliEMCALDigit | |
13 | // can (should) only store amplitude. Therefore, the SDigit energy is | |
14 | // "digitized" before being stored and must be "calibrated" back to an | |
15 | // energy before SDigits are summed to form true Digits | |
