9// PHOS digit: Id
10// energy
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!)
