To make the parton level asymmetry plots the following steps are completed.

• Make parton level di-jet trees with access to PDFs
  • At the moment focusing on DSSV2009a, since I have the needed files.  Plan to update to newer PDFs once code is working
  • code location: /global/homes/d/dolv719/DiJetMaker/run12embed/macros/DiJetTreeMaker_PythiaParton.cxx
• Read trees to make histograms for various PDFs and topologies of the detector
  • Using a class very similar to www.star.bnl.gov/webdata/dox/html/classStPythiaEvent.html
  • code location: /global/homes/d/dolv719/Systematics/TriggerBias/macros/Parton_Asymm.cxx
    • line 162 begins loop where asymmetry histograms are filled
  • This is done for each pT bin for a given run
• Combine the pT bins for a given run into one root file for said run following the same method and weights used for all other histograms
• Add histograms for all the runs and plot

Regardless of how the histogram is binned the values are approx. one order of magnitude larger than the data.
