Member Function Documentation

getCouplingConstant()

float getCouplingConstant ( const VxdID &  sensorID, const bool &  isU, const std::string &  couplingName  ) const

inline

Return coupling constant.

Input:

Parameters

sensorID	identitiy of the sensor for which the calibration is required
isU	sensor side, true for p (u) side, false for n (v) side
couplingName	coupling name, specify which coupling to return. Possible values are: "C0" | Coupling from readout implant to its readout channel "C1" | Coupling from first neighbour implant (floating) to readout channel "C2" | Coupling from second neighbour implant (readout) to readout channel "C3" | Coupling from third neighbour implant (floating) to readout channel "APVCoupling" | Coupling between two adjacent channels done at APV level after charge sharing Output: float corresponding to a given coupling constant.

        B2ERROR("Cannot find coupling constant " << couplingName << " in database.");
      }
      return coupling_constant;
    }

getElectronWeight()

float getElectronWeight ( const VxdID &  sensorID, const bool &  isU  ) const

inline

Return Geant4 electron weight.

Input:

Parameters

sensorID	identitiy of the sensor for which the calibration is required
isU	sensor side, true for p (u) side, false for n (v) side

Output: float corresponding to a Geant4-electron to real-electron weight.
