CDC Hits from CDCDigi Hits

  • the code that converts raw hits from the fADC125s of the CDC into actual CDC Hits is done in several steps:
    • the code DCDCHit_factory_Calib.cc takes the raw CDCDigiHits and create CDCHits based on the raw information. In this process the pedestal is subtracted from the signal peak amplitude and the integral and in addition the amplitude is converted into an energy based on calibration data. A code snipet of this procedure is shown below:
      double amp = amp_a_scale*gain*double(maxamp);
