 Here, also few lines of TestEm3, in SteppingAction:

  //here we are in an absorber. Locate it
  //
  G4int absorNum  = prePoint->GetTouchableHandle()->GetCopyNumber(0);
  G4int layerNum  = prePoint->GetTouchableHandle()->GetCopyNumber(1);

  G4AnalysisManager::Instance()->FillH1(MaxAbsor+absorNum, 
					  G4double(layerNum+1), edep);
