Recalibration at cell level

The workflow recalibrates a cell vector (with corresponding trigger records) for a given timeframe. The following calibrations are supported:

Bad channel calibration
Time calibration
Gain (energy) calibration Calibration objects are handled automatically via the CCDB. Calibrations must be enabled manually and are only applied in case the calibration objects exists in the CCDB.

While the energy and time calibration only change values within a cell the bad channel calibration decides whether a cell is accepted. Therefore the amount of cells can change for the given trigger. New trigger record objects are created and published to the same subspec as what is used for the output cell vector.

Definition at line 61 of file CellRecalibratorSpec.h.

Constructor & Destructor Documentation

◆ CellRecalibratorSpec()

CellRecalibratorSpec::CellRecalibratorSpec	(	uint32_t	outputspec,
		LEDEventSettings	ledsettings,
		bool	badChannelCalib,
		bool	timeCalib,
		bool	gainCalib,
		bool	isMC,
		std::shared_ptr< CalibLoader >	calibHandler
	)

Constructor.

Parameters

outputspec	Subspecification under which the output is posted
ledsettings	Handling of cells from LED events
badChannelCalib	If true the bad channel calibration is enabled
timeCalib	If true the time calibration is enabled
gainCalib	If true the gain calibration is enabled
isMC	If true the MCLabelContainer is adapted
calibHandler	Handler for calibration object loading

Definition at line 26 of file CellRecalibratorSpec.cxx.

◆ ~CellRecalibratorSpec()

o2::emcal::CellRecalibratorSpec::~CellRecalibratorSpec ( )

finaldefault

Destructor.

Member Function Documentation

◆ finaliseCCDB()

void CellRecalibratorSpec::finaliseCCDB	(	framework::ConcreteDataMatcher &	matcher,
		void *	obj
	)

finalvirtual

Fetching cell objects and assigning them to the internal handlers.

Parameters

matcher	Data type matcher of the CCDB object
obj	Pointer to CCDB object loaded

Loading CCDB object into internal cache for the 3 supported CCDB entries (bad channel map, time calibration params, gain calibration params). Objects are only loaded in case the calibration type was enabled.

Reimplemented from o2::framework::Task.

Definition at line 146 of file CellRecalibratorSpec.cxx.

◆ init()

void CellRecalibratorSpec::init ( framework::InitContext & ctx )

finalvirtual

Initialize recalibrator.

Parameters

ctx	Init context

Reimplemented from o2::framework::Task.

Definition at line 33 of file CellRecalibratorSpec.cxx.

◆ isRunBadChannlCalibration()

bool o2::emcal::CellRecalibratorSpec::isRunBadChannlCalibration ( ) const

inline

Check if the bad channel calibration is enabled.

Returns: True if the bad channel calibration is enabled, false otherwise

Definition at line 115 of file CellRecalibratorSpec.h.

◆ isRunGainCalibration()

bool o2::emcal::CellRecalibratorSpec::isRunGainCalibration ( ) const

inline

Check if the gain calibration is enabled.

Returns: True if the gain calibration is enabled, false otherwise

Definition at line 123 of file CellRecalibratorSpec.h.

◆ isRunTimeCalibration()

bool o2::emcal::CellRecalibratorSpec::isRunTimeCalibration ( ) const

inline

Check if the time calibration is enabled.

Returns: True if the time calibration is enabled, false otherwise

Definition at line 119 of file CellRecalibratorSpec.h.

◆ run()

void CellRecalibratorSpec::run ( framework::ProcessingContext & ctx )

finalvirtual

Run recalibration of cells for a new timeframe.

Parameters

ctx	Processing context

Iterates over all triggers in the timeframe and recalibrates cells. Only calibrations which are enabled are applied. Calibrated cells and new trigger records are posted at the end of the timeframe to the subspecification requested in the constructor using standard types for cells and trigger records

Implements o2::framework::Task.

Definition at line 57 of file CellRecalibratorSpec.cxx.

◆ setRunBadChannelCalibration()

void o2::emcal::CellRecalibratorSpec::setRunBadChannelCalibration ( bool doRun )

inline

Switch for bad channel calibration.

Parameters

doRun If true the bad channel calibration is applied

Definition at line 103 of file CellRecalibratorSpec.h.

◆ setRunGainCalibration()

void o2::emcal::CellRecalibratorSpec::setRunGainCalibration ( bool doRun )

inline

Switch for the gain calibration.

Parameters

doRun If true the gain calibration is applied

Definition at line 111 of file CellRecalibratorSpec.h.

◆ setRunTimeCalibration()

void o2::emcal::CellRecalibratorSpec::setRunTimeCalibration ( bool doRun )

inline

Switch for time calibration.

Parameters

doRun If true the time calibration is applied
