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.
Definition at line 29 of file AliAnalysisTaskChargedParticlesRef.h.
Direction of the beams in an asymmetric collision system.
In case of an asymmetric collision system, a rapidity shift is applied to convert from the lab frame to the centre-of-mass frame. This enum is used to determine the sign of the rapidity shift.
