Class DescriptionBrDriverDC is a BRAHMS class for serving the real geometry of T3, T4 and T5 detectors. This geometry directly refers to the construction properties of these detectors. NOTE: the units assumed in this code are in [cm]. BrDriverDC(const Char_t *Name,const Char_t *Title) :TNamed(Name,Title) void Init() Here we define some parameters that describe construction of the DCs. void ShowWord() Float_t ZfromDCFront( ) void ShowPlaneSpecif() prints plane specifications on STDOUT Float_t GetAngle() Float_t SubModulePlanePosition() This Function returns the plane Z position. This position is in respect to the center point of the module we are just now At. Float_t PlanePosition() This Function returns the Z position of plane. This position is in respect to the center point of the whole DC detector (T3, T4 or T5). Float_t GetPlanePosition(Int_t imod, Int_t iplane) This Function returns the Z position of plane. This position is in respect to the center point of the whole DC detector (T3, T4 or T5). Int_t VirtualNumber(Int_t wire) This function returns the wire position which is the distance between the wire and the center of the West-North Positioning Pin. Float_t WirePosition(Int_t wire) This function returns the wire position which is the distance between the wire and the center of the West-North Positioning Pin. Int_t WireStatus(Int_t wire) This function returns status of the particular channel:
0 - when the channel 'GlobalChan' is empty
1 - when the channel 'GlobalChan' is connected to existed wire
Float_t WireEndPoints(Int_t wire) This function calculate wire end points coordinates and return the length of wire void AtSubModule(Int_t modulNum) This function set the pointer to the Submodule numbered 'modulNumb' void AtPlane(Int_t planeNum) This function set the pointer to the plane numbered 'planeNum'. This function will be changed in the future !!! void At(Int_t modulNum, Int_t planeNum) This function set the pointer to the Submodule numbered 'modulNumb' and to the plane numbered 'planeNum'. void SetMode(Int_t i) Int_t GetMode( ) void SetDetectorTrack(Float_t* trPar) Use this method when your initial track parameters are defined in local Detector frame. void SetSubModuleTrack(Float_t* trPar) Use this method when your initial track parameters are defined in local SubModule frame. void ShowTrack() This method print parameters of the actual track defined in the center of the detector frame. if(GetZPosRef()) { Float_t z = (1-fModuleNumber) * fModuleDisp; Float_t x = fAx*z + fX0; Float_t y = fAy*z + fY0; cout<<"track1 (ax,ay,x0,y0): "<<fAx<<" "<<fAy<<" "<<x<<" "<<y<<endl; } else { cout<<"track0 (ax,ay,x0,y0): "<<fAx<<" "<<fAy<<" "<<fX0<<" "<<fY0<<endl; } Float_t* GetTrack() This method returns pointer to the vector that contains the actual track parameters defined in the center of detector frame (local detector track). /if(GetZPosRef()) { Float_t z = (1-fModuleNumber) * fModuleDisp; fTrParam[2] = fAx*z + fX0; // now fTrParam are define in center of the detector frame fTrParam[3] = fAy*z + fY0; void GoThroughModule(Int_t* wires, Float_t* xdrifts) void GoThroughPlane(Int_t& wire, Float_t& xdrift) This function looks for the wire that has the smallest distance to the track defined by 'ax', 'ay', 'x0', 'y0'. This is for module 'ModulNum' and plane 'planeNum' (see function 'SimulMode'). This wire number and distance between wire and track are indicated by 'wire' and 'xdrift', respectively. Float_t HitToWireDist(Int_t iw) This function return the distance between the particular track and the wire numbered 'iw'. The track should be previously defined by calling the function ReadTrack with the actual track parameters: fAx, fAy, fX0, fX0. If the hit is out the plane active area it returns value '-1' void DefineCorrections() Int_t LineAcceptanceStatus(BrLine3D line,Int_t opt) This method returns line acceptance status defined in the following way: 0 - line out of detector acceptance 1 - line within acceptance only at detector entry or only at detector exit 2 - line within acceptance at entry and at exit Float_t GetWirePosition(Int_t iw) This function return the distance between the center of the plane and the wire numbered 'iw'. first define correction for planes Bool_t ReadCuts() Here we open a file with cuts for a given run This cuts alow to remove noisy areas in the Time vs SignaWidth plane. Bool_t HitIsOK(Int_t it,Int_t iw) This method check whether a given hit is from noise or from clean Time vs HitWidth region. It also impose common requirement on hit's width and hit's time cout<<"In HitIsOK: "<<it<<" "<<GetMinTdc()<<" "<<GetMaxTdc()<<endl; void ReadCalibData(TString CalibFile,Int_t CalibChan) This method read matrix from the disk void ReadOffsets(TString OffsetFile, Int_t globalTdcOffset) This method read matrix from the disk Float_t GetDriftDist(Int_t im,Int_t ip,Int_t iw,Int_t il) void SetRunNumber(Int_t irun) This function define number of operating plane and detection efficiency for given run. void SetMatchCondition(Int_t ik, Float_t ASig) Here you define minimum number of planes with hit that matches a given global track. void SetMatchCondition(Float_t fraction) Float_t GetMatchEfficiency() Double_t Sil(Int_t n) void ResetMatchingStuff() Bool_t CheckIfMatch(Float_t dev, Int_t iplane) Bool_t CheckIfMatch(Float_t proj, Int_t imodule, Int_t iplane, Int_t iwire) Bool_t GetMatchingStatus() Inline Functions
