Post-BeamTest Progress on Physics

• Working from example provided in
• ORCA_8_4_0/src/Examples/Statistics/ExDSTStatisti
  cs.cpp
• We expanded this example script to fill ROOT
  branches with RecCollection data.
• In particular, each new branch in the ROOT tree
  contains data for a particular physics object
  described by the corresponding RecCollection.
• An analysis class was also created which creates
  TLorentzVector objects from the data contained in
  the branches. Histograms are also filled in the
  class.
• ExDSTStatistics.cpp contains a large, but not
  exhaustive list of RecCollections one can
  reconstruct from Digis or DSTs. So far, weve
  only looked at a subset of these.
• Ran over SUSY LM5 digis at UAF.
