Detailed Description

Gamma-ray calibration class.

Used as interface to MySQL, this class contains calibrations for ADCs, leading-edge and constant-fraction TDCs, as these are the modules that output data into the gamma-ray memories.

• The following fields are needed:
  1. ADC map
  2. ADC offset
  3. ADC gain
  4. ADC histogram map
  5. leading-edge TDC map
  6. leading-edge TDC offset
  7. leading-edge TDC gain
  8. leading-edge TDC histogram map
  9. constant-fraction TDC map
  10. constant-fraction TDC offset
  11. constant-fraction TDC gain
  12. constant-fraction histogram map

Constructor & Destructor Documentation

TGrCalibration (  UInt_t  channels = 1  )

Default constructor. Sets the size of the ADC and TDC calibrations (defaults to 1 but would be 32 for a DSSSD for example). Parameters: [in]  channels  The number of channels the detector to calibrate has. Definition at line 39 of file TGrCalibration.cxx.

~TGrCalibration (   )

Default destructor. Definition at line 51 of file TGrCalibration.cxx.

Member Function Documentation

void Clear (  const Char_t *  option = ""  )

Utility method to clear out the calibration. Parameters: [in]  option  The option is currently unimplemented. Definition at line 57 of file TGrCalibration.cxx. References TCalibration::Clear(), fAdc, fCfTdc, and fLeTdc.

Here is the call graph for this function:

void Print (  const Char_t *  option = ""  )  const

Print data held in this class. The option is currently unimplemented. Prints out leading-edge and constant-fraction TDC data, and ADC data. Parameters: [in]  option  The option is currently unimplemented. Definition at line 68 of file TGrCalibration.cxx. References fAdc, fCfTdc, fLeTdc, and TCalibration::Print().

Here is the call graph for this function:

void FindCalibration (  const Char_t *  detectorName = 0  )

Set the detector calibration, this depends on the detector name. This is an interface to MySQL, currently using TMySQL ROOT library. Parameters: [in]  detectorName  The detector to look for. Definition at line 84 of file TGrCalibration.cxx. References TCalibration::AddToChannel(), TCalibration::AddToGain(), TCalibration::AddToHistogramMap(), TCalibration::AddToMap(), TCalibration::AddToOffset(), fAdc, fCfTdc, fLeTdc, TCalibration::GetChannels(), GetDatabaseInfo(), and TCalibration::SetBitMask().

Here is the call graph for this function:

void SetDatabase (  const Char_t *  database  )  [inline]

Set the database from where the calibration data is accessed. Parameters: [in]  database  The name of the database, for example "mysql://localhost:3306/dragon". Definition at line 47 of file TGrCalibration.h. References fDatabase.

const TCalibration & GetAdc (   )  const [inline]

Get the gamma-ray ADC calibration. Returns: A calibration associated with the gamma-ray ADCs. Definition at line 56 of file TGrCalibration.h.

const TCalibration & GetLeTdc (   )  const [inline]

Get the gamma-ray leading-edge TDC calibration. Returns: A calibration associated with the gamma-ray leading-edge TDCs. Definition at line 64 of file TGrCalibration.h.

const TCalibration & GetCfTdc (   )  const [inline]

Get the gamma-ray constant-fraction TDC calibration. Returns: A calibration associated with the gamma-ray constant-fraction TDCs. Definition at line 73 of file TGrCalibration.h.

TMySQLResult * GetDatabaseInfo (  const Char_t *  detectorName = 0  )

Get the detector calibration from the MySQL database. This depends on the detector name passed in the character string detectorName. A corresponding entry will be looked for in the MySQL database and the TMySQLResult returned. If it fails an error will be printed. Parameters: [in]  detectorName  The detector name to look for. Returns: The TMySQLResult from the query if successful, otherwise a default calibration is used. Definition at line 165 of file TGrCalibration.cxx. References fDatabase.
