void AliEmcalMCTrackSelector::SetChargedMC ( Bool_t c = kTRUE )

Select only charged particles.

Parameters

c	If true only charged particles are selected

Set the eta acceptance.

Parameters

e	Maximum eta acceptance

Definition at line 102 of file AliEmcalMCTrackSelector.h.

void AliEmcalMCTrackSelector::SetOnlyPhysPrim ( Bool_t s )

inline

Select only physical primary particles.

Parameters

s	If true only physical primary particles are used

Referenced by AddTaskMCTrackSelector().

void AliEmcalMCTrackSelector::SetParticlesOutName ( const char * name )

inline

Set the name of the output container.

This container is attached to the input event with the corresponding name. This name has to be used in the user tasks to connect the MC particle container to the particles selected by this instance of the task.

Parameters

name	Name of the output container attached to the input event

Definition at line 113 of file AliEmcalMCTrackSelector.h.

Referenced by AddTaskMCTrackSelector().

void AliEmcalMCTrackSelector::SetRejectNK ( Bool_t r = kTRUE )

inline

Reject neutrons and K0long particles.

Parameters

r	If true neutrons and K0long particles are rejected

Referenced by AddTaskMCTrackSelector().

void AliEmcalMCTrackSelector::SetRejectPhotonMother ( bool doReject )

inline

Reject photon in case it is the mother of another photon.

In order to mimic processes PYTHIA8 puts mothers and daugthers of the process on the stack, which can lead in case of photons to double counting. Photon mothers that are duaghters of photon mothers need to be rejected.

Parameters

doReject If true photons are rejected if they are mothers of other photons

Definition at line 100 of file AliEmcalMCTrackSelector.h.

void AliEmcalMCTrackSelector::UserCreateOutputObjects ( )

inlineprotected

Creating user output.

Not used in this task

Definition at line 135 of file AliEmcalMCTrackSelector.h.

void AliEmcalMCTrackSelector::UserExec ( Option_t * option )

protected

Main event loop.

Run selection of particles and convert them to AliAODMCParticles and copy them to the output container. Set AliEmcalMCTrackSelector::AccpetParticle for the definition of selected particles.

Parameters

option Not used
