Detailed Description

Implement virtual track selection for AOD analysis.

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

Definition at line 34 of file AliEmcalTrackSelectionAOD.cxx.

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

Constructor, initalising track cuts depending on the requested type of filtering

Parameters

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

Definition at line 69 of file AliEmcalTrackSelectionAOD.cxx.

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

Main Constructor, initalising 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

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

Definition at line 52 of file AliEmcalTrackSelectionAOD.cxx.

Member Function Documentation

void AliEmcalTrackSelectionAOD::AddFilterBit ( UInt_t filterbits )

inline

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

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

virtual

Automatically generates track cuts depending on the requested type of filtering

Parameters

type	Track filtering type

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

static

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

Parameters

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

Returns: true if successful, false otherwise

bool AliEmcalTrackSelectionAOD::IsTrackAccepted ( AliVTrack *const trk )

virtual

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.
