Detailed Description

Simple monitoring task for cell related quantities.

Author: Markus Fasel marku.nosp@m.s.fa.nosp@m.sel@c.nosp@m.ern..nosp@m.ch, Lawrence Berkeley National Laboratory

Since: May 19, 2016

This task monitors simple cell quantities like

Amplitude distribution
Time distribution
Count rate in col-row space
Integrated amplitude in col-row space In addition, in case the task has access to reconstructed clusters, it plots
Frequency of a cell contributing to clusters
Summed cell amplitude fraction in a cluster In order to switch on cluster handling a cluster input container needs to be provided:

...

task->SetNameClusterContainer("caloClusters");

Note: When working with the default branches the names are:

caloClusters for ESDs
CaloClusters for AODs

The task should run separately for different trigger classes. This is handled in the event selection provided from outside:

...
// Selecting EMCAL gamma triggered events, high threshold
task->SetRequestTrigger(AliVEvent::kEGA, "EG1");

It can be added to the train using the add macro

Member Function Documentation

void AliEmcalCellMonitorTask::CreateHistograms ( )

protected

Create the output histograms

For all supermodules the following histograms will be created:

cellAmplitude with the cell amplitude distribution
cellTime with the cell time distribution

For each supermodule the following histograms will be created:

cellAmpSM with the integrated amplitude for cells within a supermodule in col and row
cellCountSM with the count rate for cells within a supermodule in col and row

Function is called in ExecOnce

Definition at line 163 of file AliEmcalCellMonitorTask.cxx.

Referenced by ExecOnce().

void AliEmcalCellMonitorTask::ExecOnce ( )

protectedvirtual

Perform initializations of the task which require a run number (only available as soon as the first event is available). This contains:

Loading EMCAL geometry
Creating histograms As the dimension for most of the histograms is based on the amount of cells, which is obtained from the EMCAL geometry, the histograms are not initialized in UserCreateOutputObjects but in ExecOnce.

void AliEmcalCellMonitorTask::InitBadChannelsFromContainer ( const TString & containername )

inline

Read bad channels from OADB container and set the cell with the ID as bad.

Parameters

[in] containername Name of the OADB container.

Definition at line 121 of file AliEmcalCellMonitorTask.h.

bool AliEmcalCellMonitorTask::IsCellMasked ( Int_t cellId ) const

protected

Check whether cell with a given ID is masked by the user

Parameters

cellId Cell ID to be checked

Returns: True if the cell is masked, false otherwise

void AliEmcalCellMonitorTask::LoadCellMasking ( )

protected

Load the cell masking from the OADB container into the task

AliEmcalCellMonitorTask& AliEmcalCellMonitorTask::operator= ( const AliEmcalCellMonitorTask & ref )

private

void AliEmcalCellMonitorTask::RunChanged ( )

protectedvirtual

Perform tasks necessary when the run number changes. In this case a new masked cell map is loaded and masked cells are marked in a historgam.

void AliEmcalCellMonitorTask::SetBadCell ( Int_t cellId )

Mark cell as bad (i.e) exclude from running

Parameters

cellId Cell to be masked

void AliEmcalCellMonitorTask::SetMinCellAmplitudeForCellTime ( Double_t minAmp )

inline

Set the minimum amplitude requested for a cell in order to use the cell time in the cell time plot

Parameters

minAmp Min. cell amplitude

Definition at line 82 of file AliEmcalCellMonitorTask.h.

void AliEmcalCellMonitorTask::SetNameClusterContainer ( const TString & nameclusters )

inline

Set the name of the cluster container. If provided the following additional histograms will be provided:

Occurrency of a cell inside clusters: cellClusterOccurrency
Summed energy distribution of a cell in clusters: cellSumAmplitudeCluster In case of the summed energy the value is calculated summing up the energy of all occurrences within one cluster
Parameters

[in] nameclusters Name of the cluster container

Definition at line 114 of file AliEmcalCellMonitorTask.h.

void AliEmcalCellMonitorTask::SetRequestTrigger	(	ULong_t	triggerbits,
		TString	triggerstring = `""`
	)

inline

Define trigger selection. It can consist of trigger bits and a trigger string

Parameters

triggerbits	Trigger bit selection
triggerstring	Trigger string (i.e. EG1, EG2, DG1, ...)

Definition at line 89 of file AliEmcalCellMonitorTask.h.

void AliEmcalCellMonitorTask::SetRun2 ( )

inline

Set number of Cells in order to match run2 geometry

Definition at line 97 of file AliEmcalCellMonitorTask.h.

void AliEmcalCellMonitorTask::UserCreateOutputObjects ( )

protectedvirtual

Prepare histogram manager for later initialization. As the histograms depend on the number of cells which is available only for after the first event is initialized, the histograms are not created here but in ExecOnce.

Definition at line 76 of file AliEmcalCellMonitorTask.cxx.

void AliEmcalCellMonitorTask::UserExec ( Option_t * )

protectedvirtual

Event loop.

Running over all cells and filling the cell-related quantities specified in the class documentation.

Parameters
