Detailed Description

This plugin runs over the events, selects the recHits according to the criteria defined in addRecHit

Todo:: Exit condition based on convergence

Member Function Documentation

bool EcalTimingCalibProducer::addRecHit	(	const EcalTimingEvent &	recHit,
		EventTimeMap &	eventTimeMap_
	)

private

The recHit is used (accepted) if:

recHit flag in the list of _recHitFlags defined in the config file
recHit energy in EB > _minRecHitEnergy defined in the config file
recHit energy in EE is x2 the threshold of EB
at each iteration the recHit threshold is raised by _minRecHitEnergyStep If the recHit is used, the time information is added to _eventTimeMap

References _eventTimeMap, and EcalTimingEvent::energy().

Here is the call graph for this function:

EcalTimingEvent EcalTimingCalibProducer::correctGlobalOffset	(	const EcalTimingEvent &	te,
		int	splashDir,
		float	bunchCorr
	)

private

Returns an EcalTimingEvent with a new time, which has been adjusted so that the upstream endcap is 0.

Parameters

[in]	te	EcalTimingEvent
[in]	splashDir	integer indicating the beam direction in splash events
[in]	bunchCorr	float correction for global event timing
[out]	c	corrected timing event
