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