Correct background bias in full dimensional space
We now assume 4bSB / 3bSB == 4bSR / 3bSR.
If we measure and correct bias with the synthetic data. we would then only assume a double ratio holds: rSR / rSB (data) == rSR / rSB (synthetic data)
How to measure and correct the bias
- Measure ration of 1D (SvB) projection vs
- Measure bias in full phase space with a Bkg vs Synthetic Data classifier (like FvT)
Bkg = wSvD x wFvT x wJCM
