The cut should remove any events that have 2 or more non-Hbb fatjets with Wqq scores above 0.8

Logic for cut:
Compute number of fatjets per event with Wqq score > 0.8. Define cut as true for event if there are less than 3 such fatjets, and in the case that there are exactly two, define cut as true iff Hbb is one of them

To study this would I want to run over a large number of signal files (C2V = 0)? it seems like this cut is pretty rare from the several files that I tested. For background, would I use TTToSemiLeptonic as well?

Looking good, I had to update the discriminant to match the one used in the semi-resolved analysis. @andresnava1000 Could you check the efficiency of a selection on NumWTagged >= 2 for QCD, TT, and the HH signals? I think just one file each should be enough.

Variables are looking OK, will need to iterate on the exact veto with Amitav. See https://indico.cern.ch/event/1375175. For now, saving the SD and regressed masses of the two W-tagged jets.
