Description
Uncertainties in NLO calculations are often estimated by variations of
the renormalization scale. The same can be done in parton showers. I
talk about the consistent treatment of renormaliztion scale variations
in the unitary merging of NLO matrix element calculations and parton
showers. Furthermore, I discuss some freedom in reweighting NLO
corrections and compare different unitary merging prescriptions.
