I have replacated my W analysis using the Fisher Discriminant method in the TMVA package for ROOT.

Figure 1: Signal correlation matrix

Figure 2: Background correlation matrix

Figure 3: Signal and background distributions for cut quantities

Figure 4: Signal - background seperation (program)

Figure 5: Signal - background seperation (by-hand)

I have compiled the 3x3 patch ET spectrum for several values of the Fisher discriminant value here.
