◆ countDuplicatedAfterCuts()

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

excluding external z

excluding the gap between two chips in the same stave (comment to obtain the plot efficiency col vs eta)

Definition at line 838 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 2532 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 2837 of file Efficiency.cxx.

◆ getDCAClusterTrackMC()

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

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 598 of file Efficiency.cxx.

◆ getEfficiency()

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

filling some chip maps

excluding external z

excluding the gap between two chips in the same stave (comment to obtain the plot efficiency col vs eta)

if the track passes the cuts, 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 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 2179 of file Efficiency.cxx.

◆ init()

void o2::its::study::EfficiencyStudy::init ( InitContext & context )

finalvirtual

The method which is called once to initialise the task. Derived classes can use this to save extra state.

Reimplemented from o2::framework::Task.

Definition at line 326 of file Efficiency.cxx.

Definition at line 2493 of file Efficiency.cxx.

◆ run()

void o2::its::study::EfficiencyStudy::run ( ProcessingContext & context )

finalvirtual

This is invoked whenever a new InputRecord is demeed to be complete.

◆ 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

all Row

all Col

all Z

all Eta

all Phi

◆ 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
