Bob has plots of energy and rphi distributions and fits for Z-mu mu and W candidates. The normalization of the fit to the W drphi uses a gaussian and a scaled copy of the z drphi peak. Normalization is only for the central 5 bins (the only things he keeps as W's). Note that the yields cannot be directly compared between W and Z because they come from different streams. The asymmetry numbers quoted there assume the background has not asymmetry. The lower plots have looser cuts (on the left) and events from bhmu stream (on the right) which had CMUX trigger w/BMU muon. Asymmetry in this small ribbon is .110+- .032. He also gives some description of the cuts, which differ from those given last time (includes energy in calorimeter left by muon). The second page looks at the west and east fits, to see if the backgrounds are asymmetric: and they are.
