//_________________________________________________________________________
//  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 TClonesArray,
//   it is not possible to stream such an array... (beyond my understqnding!)
