  • Formula for ADC (Fast simulator)
    t->energy() stands for total GEANT energy deposit in given tower/pre/post/strip in GeV
    towers:
      msamplingFraction=0.05;
      // towers are gain matched to fixed E_T
      const int maxAdc=4095;
      const int maxEtot=60;  // in GeV
      const float feta[kEEmcNumEtas]= {1.95,1.855,1.765,1.675,1.59,1.51,1.435,1.365,1.3,1.235,1.17,1.115}; 
      
    
      mfixTgain=new float [kEEmcNumEtas];
      for (i=0;i< kEEmcNumEtas;i++) {
        mfixTgain[i]=maxAdc/maxEtot/cosh(feta[i])/msamplingFraction;
      }
    
    
      int adc=(int) (t->energy() * mfixTgain[eta-1]);
    

    pre/post :

      mfixPgain=23000;
    
      int adc= (int) (t->energy()* mfixPgain);
    
    SMD:
      mfixSMDgain=23000;
      int adc= (int) (t->energy()* mfixSMDgain);
