  // ------>>>> IMPORTANT!!!!
  // For a correct comparison between GEANE and MC (pull distributions) 
  // or for a simulation without the generation of secondary particles:
  // 1. set LOSS = 2, DRAY = 0, BREM = 1
  // 2. set the following cut values: CUTGAM, CUTELE, CUTNEU, CUTHAD, CUTMUO = 1 MeV or less
  //                                  BCUTE, BCUTM, DCUTE, DCUTM, PPCUTM = 10 TeV
  // (For an explanation of the chosen values, please refer to the GEANT User's Guide
  // or to message #5362 in the PandaRoot Forum >> Monte Carlo Engines >> g3Config.C thread)
  // 
  // The default settings refer to a complete simulation which generates and follows also the secondary particles.
