First attempt of QCD shape computation
QCD shape computation:
- Added data samples in config/test.py and data process in processes.py
- Including in FeatureTask parameter do_QCD
- Including in featurePlot function the QCD shape computation. OK when stack=False, pending to test when stack=True (not having the good samples and training yet). In any case, it's at the end of the chain and it should be transparent if do_QCD = False
Other changes:
- Added ggH_xs sample (same sample than lambdarew11 but with the proper xs)
- Added regions in config/test_2017.py in order to easily compute QCD shape and normalization.
