Detailed Description

template<class ParSet>
class BSEmcExtractDigisFromWaveforms< ParSet >

Task to create digis from waveforms.

This is an alternative to BSEmcWaveformToDigi, which despite its name could be used for all the EMC, not just FwEndcap.

protectedpure virtual

Implemented in BSEmcFwEndcapDigi, BSEmcBwEndcapDigi, and BSEmcShashlykDigi.

Referenced by BSEmcExtractDigisFromWaveforms< BSEmcFwEndcapDigiPar >::GetTimeStamp(), and BSEmcExtractDigisFromWaveforms< BSEmcFwEndcapDigiPar >::Init().

◆ Exec()

template<class ParSet>

virtual void BSEmcExtractDigisFromWaveforms< ParSet >::Exec ( Option_t * )

inlinevirtual

Runs the task.

The task loops over the waveforms and uses the pulse shape analyser (BSEmcAbsPSA) to extract signal height and timing. If the energy is above the threshold (fEnergyDigiThreshold), a BSEmcDigi is created.

Parameters

opt unused

Returns: void
