Detailed Description

Implement virtual track selection for AOD analysis.

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

Date: Jul 24, 2015

Implementation of track selection in case the analysis runs on AODs For the moment it uses the AliESDtrackCuts and converts AOD tracks to ESD tracks, which might change in the future when an AOD track selection framework becomes available.

Constructor & Destructor Documentation

AliEmcalTrackSelectionAOD::AliEmcalTrackSelectionAOD ( )

Main constructor.

Initializes fields with 0 (or NULL). For ROOT I/O, not intended to be used by the users.

Definition at line 54 of file AliEmcalTrackSelectionAOD.cxx.

AliEmcalTrackSelectionAOD::AliEmcalTrackSelectionAOD	(	ETrackFilterType_t	type,
		const char *	period = `""`
	)

Constructor for periods.

Initializing track cuts depending on the requested type of filtering

Parameters

[in]	type	Track filtering type
[in]	period	Period string (e.g. LHC11h)

Definition at line 70 of file AliEmcalTrackSelectionAOD.cxx.

AliEmcalTrackSelectionAOD::AliEmcalTrackSelectionAOD	(	AliVCuts *	cuts,
		UInt_t	filterbits
	)

Main Constructor.

Initalizing also track cuts and filter bits. In case the initial cuts is a nullpointer, only filter bits are used for the track selection. This constructor is intended to be used by the users.

Parameters

[in]	cuts	Inital track cut object (of type AliESDtrackCuts, can be a nullpointer)
[in]	filterbits	Filter bits required

Definition at line 59 of file AliEmcalTrackSelectionAOD.cxx.

virtual AliEmcalTrackSelectionAOD::~AliEmcalTrackSelectionAOD ( )

inlinevirtual

Destructor.

Definition at line 85 of file AliEmcalTrackSelectionAOD.h.

Member Function Documentation

void AliEmcalTrackSelectionAOD::AddFilterBit ( UInt_t filterbits )

Add a new filter bit to the track selection.

Multiple filter bits can be set at the same time (via the bitwise or operator |).

Parameters

filterbits Filter bits used to select tracks

void AliEmcalTrackSelectionAOD::GenerateTrackCuts	(	ETrackFilterType_t	type,
		const char *	period = `""`
	)

virtual

Automatically generates track cuts depending on the requested type of filtering.

Parameters

[in] type Track filtering type

Implements AliEmcalTrackSelection.

Bool_t AliEmcalTrackSelectionAOD::GetHybridFilterBits	(	Char_t	bits[],
		TString	period
	)

static

Returns the hybrid filter bits according to a hard-coded look-up table.

Parameters

[in]	bits	c-array of 2 elements where the bits are returned
[in]	period	data taking period

Returns: true if successful, false otherwise

PWG::EMCAL::AliEmcalTrackSelResultPtr AliEmcalTrackSelectionAOD::IsTrackAccepted ( AliVTrack *const trk )

virtual

Performing track selection.

Function checks whether track is accepted under the given track selection cuts. The function can handle AliAODTrack and AliPicoTrack, while for AliPico track an AliAODTrack is expected to be the underlying structure. If it is not possible to access an AOD track from the input track, the object will not be selected. Otherwise first the status bits are checked (if requested), and if further track cuts (of type AliESDtrackCuts) are provided, the track is converted to an ESD track for further checks.

Parameters

[in] trk Track to check

Returns: true if selected, false otherwise

Implements AliEmcalTrackSelection.
