Nilsen // July 11 1999 // // AliITShit is the hit class for the ITS. Hits are the information // that comes from a Monte Carlo at each step as a particle mass through // sensitive detector elements as particles are transported through a // detector. // // Data members: // // Int_t fTrack // See AliHit for a full description. The track number of the track // that made this hit. // // Float_t fX // See AliHit for a full description. The global x position of the // hit (in the standard units of the Monte Carlo). // // Float_t fY // See AliHit for a full description. The global y position of the // hit (in the standard units of the Monte Carlo). // // Float_t fZ // See AliHit for a full description. The global z position of the // hit (in the standard units of the Monte Carlo). // // Int_t fStatus // The track status flag. This flag indicates the track status // at the time of creating this hit. It is made up of the following 8 // status bits from highest order to lowest order bits // 0 : IsTrackAlive(): IsTrackStop():IsTrackDisappeared(): // IsTrackOut():IsTrackExiting():IsTrackEntering():IsTrackInside() . // See AliMC for a description of these functions. If the function is // true then the bit is set to one, otherwise it is zero. // // Int_t fLayer // The layer number of the detector that contains this hit. See // AliITSgeom and AliITSv? for a description of the geometry. // // Int_t fLadder // The ladder number of the detector that contains this hit. See // AliITSgeom and AliITSv? for a description of the geometry. // // Int_t fDet // The detector number of the detector that contains this hit. See // AliITSgeom and AliITSv? for a description of the geometry. // // Float_t fPx // The x momentum, in global coordinates, of the particle that // "created" the hit at the time and position of the hit. The units // are those determined by the Monte Carlo. // // Float_t fPy // The y momentum, in global coordinates, of the particle that // "created" the hit at the time and position of the hit. The units // are those determined by the Monte Carlo. // // Float_t fPz // The z momentum, in global coordinates, of the particle that // "created" the hit at the time and position of the hit. The units // are those determined by the Monte Carlo. // // Float_t fDestep // The energy lost by the particle during the step ending in this // hit. The units are those determined by the Monte Carlo. // // Float_t fTof // The time of flight associated with the particle ending in this // hit. The time is typically measured from the point of creation of the // original particle (if this particle is a daughter). The units // are those determined by the Monte Carlo. // // //////////////////////////////////////////////////////////////////////// #include #include "AliHit.h" class TParticle; class AliITShit : public AliHit { public: AliITShit();// Default consrtructor // Old Standard Constructor AliITShit(Int_t shunt, Int_t track, Int_t *vol, Float_t *hits); // New Standard Constructor AliITShit(Int_t shunt,Int_t track,Int_t *vol,Float_t edep,Float_t tof, TLorentzVector &x,TLorentzVector &x0,TLorentzVector &p); // Copy Constructor AliITShit(const AliITShit &h); // Equals operator AliITShit& operator=(const AliITShit &h); // Default destructor virtual ~AliITShit() {}; // Get Hit information functions. // virtual int GetTrack() const {return fTrack;} // define in AliHit // virtual void SetTrack(int track) const {fTrack=track;) // AliHit virtual void SetModule(Int_t mod){fModule=mod;}; virtual void SetShunt(Int_t shunt); virtual void SetPosition(TLorentzVector &x){fX=x.X();fY=x.Y();fZ=x.Z();} virtual void SetStartPosition(TLorentzVector &x){fx0=x.X();fy0=x.Y(); fz0=x.Z();} virtual void SetTime(Float_t t){fTof = t;} virtual void SetStartTime(Float_t t){ft0 = t;} virtual void SetStatus(Int_t stat){fStatus = stat;} virtual void SetStartStatus(Int_t stat){fStatus0 = stat;} virtual void SetEdep(Float_t de){fDestep = de;} virtual void SetMomentum(TLorentzVector &p){fPx=p.Px();fPy=p.Py(); fPz=p.Pz();} virtual Int_t GetTrackStatus() const {//returns the status code return fStatus;} virtual Int_t GetTrackStatus0() const {//returns the status code return fStatus0;} virtual Int_t GetLayer() const{Int_t a,b,c;// returns the layer number GetDetectorID(a,b,c); return a;} virtual Int_t GetLadder() const{Int_t a,b,c;// returns the ladder number GetDetectorID(a,b,c); return b;} virtual Int_t GetDetector() const{Int_t a,b,c;//returns the detector number GetDetectorID(a,b,c); return c;} // returns the detector ID virtual void GetDetectorID(Int_t &layer,Int_t &ladder,Int_t &det)const; virtual Int_t GetModule(){return fModule;}; virtual Float_t GetIonization() const {return fDestep;}//returns the Destep // virtual void GetPositionG(Float_t &x,Float_t &y,Float_t &z)const { // returns the position in the Global frame x=fX;y=fY;z=fZ;return;}; virtual void GetPositionG(Double_t &x,Double_t &y,Double_t &z)const { // returns the position in the Global frame x=fX;y=fY;z=fZ;return;}; virtual Float_t GetTOF() const {// returns the time of flight return fTof;} // Returns particle 3 position at this hit in global coordinates. virtual void GetPositionG(Float_t &x,Float_t &y,Float_t &z,Float_t &tof) const {// returns the position in the Global frame and the time of // flight x=fX;y=fY;z=fZ,tof=fTof;return;}; virtual void GetPositionG(Double_t &x,Double_t &y,Double_t &z,Double_t &t) const {// Returns particle 3 position and the time of flight at this // hit in global coordinates. x=fX;y=fY;z=fZ,t=fTof;return;}; virtual Float_t GetXG()const {// Returns particle X position at this hit // in global coordinates. return fX;} virtual Float_t GetYG()const {// Returns particle X position at this hit // in global coordinates. return fY;} virtual Float_t GetZG()const {// Returns particle Z position at this hit // in global coordinates. return fZ;} // Returns particle 3 position at this hit in global coordinates. virtual void GetPositionG0(Float_t &x,Float_t &y,Float_t &z,Float_t &tof) const {// returns the initial position in the Global frame and the // time of flight x=fx0;y=fy0;z=fz0,tof=fTof;return;}; // Returns particle 3 position at this hit in global coordinates. virtual void GetPositionG0(Double_t &x,Double_t &y,Double_t &z, Double_t &tof)const { // returns the initial position in the Global frame and the // time of flight x=fx0;y=fy0;z=fz0,tof=fTof;return;}; virtual void GetPositionL(Float_t &x,Float_t &y,Float_t &z){ // Returns particle 3 position at this hit in local coordinates.
