Hi, I had just a chat with Bob. One thing which we should also consider is how data and MC compare for the depleted sample when binning in multiplicity categories of the brecoil. Things bring me to a delicate point: I expect that the ratios of comBG/peakBG or peakBG/Sig will be different between data and MC. And I also expect that they will differ in the MC between signal and the depleted sample. If this is the case it is not obvious how to apply the data/MC comparison to the signal MC. Cheers, Heiko
