+ //////////////////////////////////////
+ //
+ // Adds the tree TD for digits (charges deposited on pads)
+ // to the ROOT file "galice.root"
+ // containing the signal hit coordinates from simulation (tree TH).
+ // Eventually (argument "ibg"), background hits are also taken into account,
+ // from the ROOT file "bg.root".
+ //
+ // Arguments:
+ // evNumber1 = first event number to digitize in file "galice.root"
+ // evNumber2 = last event number to digitize in file "galice.root"
+ // ibg = 0 if no background hits to be taken into account;
+ // = 1 if background hits to be taken into account
+ // in file "bg.root"
+ // bgr : used only if "ibg" = 1
+ // = number of events in the background file "bg.root";
+ // the signal events are divided into "bgr" successive parts,
+ // all events of each part are associated
+ // with the same background event,
+ // starting with event number 0,
+ // incrementing it by 1 for the next part.
+ // Strictly speaking, "bgr" can be smaller than
+ // the number of events in the background file,
+ // in which case one will only use
+ // the first "bgr" events of the background file.
+ // But it SHOULD NOT BE LARGER THAN
+ // THE NUMBER OF EVENTS IN THE BACKGROUND FILE.
+ //
+ // Input file(s):
+ // "galice.root" for signal
+ // "bg.root" for background (used only if "ibg" = 1)
+ //
+ // Output file:
+ // "galice.root"
