◆ countDuplicatedAfterCuts()

void o2::its::study::EfficiencyStudy::countDuplicatedAfterCuts ( )

applying the cuts on the phi of the original cluster

wether or not a cluster is found in an eligible track in the corresponding layer

if the track (cluster) is not eligible for any layer, go to the next one

Definition at line 785 of file Efficiency.cxx.

◆ endOfStream()

void o2::its::study::EfficiencyStudy::endOfStream ( EndOfStreamContext & context )

finalvirtual

This is invoked whenever we have an EndOfStream event.

Reimplemented from o2::framework::Task.

Definition at line 2678 of file Efficiency.cxx.

◆ finaliseCCDB()

void o2::its::study::EfficiencyStudy::finaliseCCDB	(	ConcreteDataMatcher &	matcher,
		void *	obj
	)

finalvirtual

This is invoked whenever a new CCDB object associated to a given ConcreteDataMatcher is deserialised

Reimplemented from o2::framework::Task.

Definition at line 2827 of file Efficiency.cxx.

◆ getDCAClusterTrackMC()

int o2::its::study::EfficiencyStudy::getDCAClusterTrackMC ( int countDuplicated = 0 )

compute the distance between original and dubplicated cluster

Compute the DCA between the cluster location and the track

first propagate to the original cluster

then propagate to the duplicated cluster

Definition at line 536 of file Efficiency.cxx.

◆ getEfficiency()

void o2::its::study::EfficiencyStudy::getEfficiency ( bool isMC )

the cut on phi, since it is layer-dependent, can be applied only after finding the cluster and then the layer

applying the cuts on the phi of the original cluster

wether or not a cluster is found in an eligible track in the corresponding layer

if the track (cluster) is not eligible for any layer, go to the next one

fill the den and go ahead

if the cuts up to here are passed, then search for the duplicated cluster, otherwise go to the next cluster

for each original cluster iterate over all the possible duplicated clusters to see first wether increment or not the denominator (if a track has a possible duplicated cluster in the selected phi region) then if the phi is within the cuts, select the "adjacent" clusters (stave +-1, chip =,+-1) and calculate the DCA with the track. Then choose the closest one.

if the cheks are passed, then calculate the DCA Compute the DCA between the duplicated cluster location and the track

Definition at line 2028 of file Efficiency.cxx.

◆ getEfficiencyAndTrackInfo()

void o2::its::study::EfficiencyStudy::getEfficiencyAndTrackInfo ( bool isMC )

the cut on phi, since it is layer-dependent, can be applied only after finding the cluster and then the layer

applying the cuts on the phi of the original cluster

wether or not a cluster is found in an eligible track in the corresponding layer

if the track (cluster) is not eligible for any layer, go to the next one

fill the den and go ahead

for each original cluster iterate over all the possible duplicated clusters to see first wether increment or not the denominator (if a track has a possible duplicated cluster in the selected phi region) then if the phi is within the cuts, select the "adjacent" clusters (stave +-1, chip =,+-1) and calculate the DCA with the track.

◆ studyClusterSelectionMC()

void o2::its::study::EfficiencyStudy::studyClusterSelectionMC ( )

cut on primary vertex position (?)

for each oroginal cluster iterate over all the possible "adjacten" clusters (stave +-1, chip =,+-1) and calculate the DCA with the track. Then choose the closest one.

if the cheks are passed, then calculate the DCA

Compute the DCA between the duplicated cluster location and the track

eta and phi in different pt ranges

Definition at line 1319 of file Efficiency.cxx.

◆ studyDCAcutsMC()

void o2::its::study::EfficiencyStudy::studyDCAcutsMC ( )

for each oroginal cluster iterate over all the possible "adjacent" clusters (stave +-1, chip =,+-1) and calculate the DCA with the track. Then compare the cluster label with the track label to see if it is a true or fake match

if the cheks are passed, then calculate the DCA

Compute the DCA between the duplicated cluster location and the track

checking the DCA for 20 different sigma ranges
