 //  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!)
