19 | // EMCAL digit: Id | |
20 | // energy | |
21 | // 3 identifiers for the primary particle(s) at the origine of the digit | |
22 | // The digits are made in FinishEvent() by summing all the hits in a single EMCAL crystal or PPSD gas cell | |
23 | // It would be nice to replace the 3 identifiers by an array, but, because digits are kept in a TClonesQArray, | |
24 | // it is not possible to stream such an array... (beyond my understqnding!) | |
