This required to add a flag to baseTtbbPlotter.prepareTree() to avoid adding the ttbar category cut at the root selection node, and then to modify the logic for the selections in the unfoldingPlotter:
- for ttX=ttjj/ttC: reco-level selection = (reco cuts) && (ttX category) && !(signal gen-level phase space cuts)
- for ttB:
- gen-level selection = (signal gen-level phase space cuts)
- reco-level selection = (reco cuts) && ((ttB category) || (signal gen-level phase space cuts))
- reco level for migration matrices: (reco cuts) && (signal gen-level phase space cuts)
This means that the signal gen-level cuts have to be declared even for the ttjj and ttC backgrounds.
