11 | // 3 identifiers for the primary particle(s) at the origine of the digit |
12 | // The digits are made in FinishEvent() by summing all the hits in a single PHOS crystal or PPSD gas cell |
13 | // It would be nice to replace the 3 identifiers by an array, but, because digits are kept in a TClonesQArray, |
14 | // it is not possible to stream such an array... (beyond my understqnding!) |
