Detailed Description

Unit test class for charged particle distributions.

As generator of reference distributions this task is written as "must work", meaning as simple as possible and as independent as possible. Using only well-tested components. Objects responsible for further problems, i.e. the usage of THnSparse due to memory problems in several places, are forbidden.

Double_t EMCalTriggerPtAnalysis::AliAnalysisTaskChargedParticlesRef::GetTriggerWeight ( const std::string &  triggerclass) const
protected

Get a trigger class dependent event weight. The weight is defined as 1/downscalefactor. The downscale factor is taken from the OADB. For triggers which are not downscaled the weight is always 1.

Parameters
[in]triggerclassClass for which to obtain the trigger.
Returns
Downscale facror for the trigger class (1 if trigger is not downscaled or no OADB container is available)
