Function documentation

THaScintillator(const char* name, const char* description = "", THaApparatus* a = 0)
THaScintillator( )
THaAnalysisObject::EStatus Init(const TDatime& run_time)
 Extra initialization for scintillators: set up DataDest map
Int_t ReadDatabase(const TDatime& date)
 Read this detector's parameters from the database file 'fi'.
 This function is called by THaDetectorBase::Init() once at the
 beginning of the analysis.
 'date' contains the date/time of the run being analyzed.
Int_t DefineVariables(THaAnalysisObject::EMode mode = kDefine)
 Initialize global variables and lookup table for decoder
 Destructor. Remove variables from global list.
void DeleteArrays()
 Delete member arrays. Used by destructor.
void ClearEvent()
 Reset per-event data.
Int_t Decode(const THaEvData& )
 Decode scintillator data, correct TDC times and ADC amplitudes, and copy
 the data to the local data members.
 This implementation makes the following assumptions about the detector map:
 - The first half of the map entries corresponds to ADCs,
   the second half, to TDCs.
 - The first fNelem detector channels correspond to the PMTs on the
   right hand side, the next fNelem channels, to the left hand side.
   (Thus channel numbering for each module must be consecutive.)
Int_t ApplyCorrections( void )
 Apply the ADC/TDC corrections to get the 'REAL' relevant
 TDC and ADC values. No tracking needs to have been done yet.

 Permits the dividing up of the decoding step (events could come from
 a different source) to the applying of corrections. For ease when
 trying to optimize calibrations

Double_t TimeWalkCorrection(const Int_t& paddle, const THaScintillator::ESide side)
 Calculate the time-walk correction. The timewalk might be
 dependent upon the specific PMT, so information about exactly
 which PMT fired is required.
Int_t CoarseProcess(TClonesArray& tracks)
 Calculation of coordinates of particle track cross point with scint
 plane in the detector coordinate system. For this, parameters of track
 reconstructed in THaVDC::CoarseTrack() are used.

 Apply corrections and reconstruct the complete hits.

Int_t FineProcess(TClonesArray& tracks)
 Reconstruct coordinates of particle track cross point with scintillator
 plane, and copy the data into the following local data structure:

 Units of measurements are meters.
Int_t GetNHits()
{ return fNhit; }
const Double_t* GetTimes()
{ return fTime; }
const Double_t* GetTuncer()
{ return fdTime; }
const Double_t* GetAmplitudes()
{ return fAmpl; }
const Double_t* GetYtime()
{ return fYt; }
const Double_t* GetYampl()
{ return fYa; }
Int_t GetNTracks()
{ return fTrackProj->GetLast()+1; }
const TClonesArray* GetTrackHits()
{ return fTrackProj; }
