TPC Asymmetries in 3GeV AuAu Collisions

 When analyzing the 3 GeV FastOffline data set taken this year, I notice some severe asymmetries in phi vs. eta distributions. In the attached set of slides, I show these distributions and weight them with p_{T}, nHits, and DCA to primary vertex. TpcAsymmetries.root is the file containing the histograms and can be download from: https://drive.google.com/open?id=1KO13wUbz6SSk7BO_2CsbG2VfL6_2Vu6X
The relevant plots are:
