22 | // The digits are made in FinishEvent() by summing all the hits in a single PHOS 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!) | |
