2010.01.15 W test sample QA: Pass 3

QA of the test W-sample from Lidia/Jason.
generated MuDst are from /star/data08/users/starreco/recowtest/

QA plots for the previous pass 2 can be found here

QA plots for the previous pass 1 can be found here

Two channels being analyzed:

  • wtest10000 W+ --> e+ nu (shown by black line)
  • wtest10001 W- --> e- nu (shown by red line)

Cuts: |geant_eta_lepton| < 1
