class HEmcDigitizer: public HReconstructor


  HEmcDigitizer digitizes data, puts output values into cal data category

 Input data for digitization:
 Two types of HGeantEmc objects:
 1. Hit which has track number = -777 keeps integrated number of photo electrons
 2. Hit which has track number > 0 keeps a time of flight, momentum, track length and number of photo electrons

 Parameters for recalculating of the number of photo electrons to the energy deposit
 Parameters for the time and energy deposit smearings
 Parameter for the start signal smearing

 Two modes of reconstruction: simulation and embedding

 HEmcDigitizer
  collects all tracks in the cell,
  corrects GEANT time of flight to the time in the input EMC plane,
  sorts tracks by corrected time and assigns the cell time to the fastest track which has energy deposit above threshold,
  sorts tracks by energy and assigns the cell to the track which has maximal energy deposit.

 Digitizer retrieves a particle from track history which crosses parallel plane to EMC plane and distance to front of EMC is equal to zVertBorder.
 zVertBorder >= 0    EMC front plane is used
 zVertBorder = -130. RPC front plane is used (default value)
