FMS data model

StFmsHit, StFmsCluster and StFmsPoint are the data model defined for storing FMS data in StEvent/StMuDST:

StFmsHit

protected: UShort_t mDetectorId; // Detector Id UShort_t mChannel; // Channel in the detector UShort_t mQTCrtSlotCh; // QT Crate/Slot/Ch, 4 bits for Crate and Slot, 8 bits for channal UShort_t mAdc; // ADC values UShort_t mTdc; // TDC values Float_t mEnergy; // corrected energy
StFmsCluster

protected: Int_t mDetectorId; Float_t mTotalEnergy ; // total energy contained in this cluster (0th moment) Float_t mX ; // mean x ("center of gravity") in local grid coordinate (1st moment) Float_t mY ; // mean y ("center of gravity") in local grid coordinate (1st moment) Float_t mThetaAxis; // theta angle in x-y plane that define the direction of least-2nd-sigma axis Float_t mSigmaX ; // 2nd moment in x Float_t mSigmaY ; // 2nd moment in y Float_t mSigmaMin; // 2nd sigma w.r.t to the least-2nd-sigma axis Float_t mSigmaMax; // 2nd sigma w.r.t to the axis orthogonal to the least-2nd-sigma axis StPtrVecFmsHit mHits;
StFmsPoint

protected: Int_t mDetectorId; Int_t mCategory ; // catagory (1: 1-photon, 2: 2-photon, 0: could be either 1- or 2-photon) Float_t mFittedEnergy ; // fitted energy of the hit Float_t mX ; // fitted x in local grid coordinate (1st moment) Float_t mY ; // fitted y in local grid coordinate (1st moment) Float_t mChiSquare; // Chi-square of the fitting StPtrVecFmsCluster mMotherCluster; StPtrVecFmsPoint mSiblingPoint;

StFmsCollection is the entry point to FMS related data in StEvent/StMuDST.
