Why Event plane distribution is not flat after phi weighting? Why do we need Psi-shifting?

  • phi-weighting: weight the track so that the phi distribution is flat.

Minutes:

There was a discussion about using difference between extracted tracking efficiencies for different FXT collision energies. Accoording to Gene it is not clear if separate calibrations for individual collisions energies are needed and it is being now investigated by TPC group.

From discussion of previous Robert's results on probability of hit loss on track it seem that there is higher chance to loose hits in lower pat of the TPC in data compared to simulation. This is bit strange in light of Xianglei's findings about cluster simulations as showed at collaboration meeting. It was suggested that incomplete accounting of dead channels could play a role.
