By "fast sim", you mean just the truth-level MC, right?

This is something we want, but not currently available.

I think that's the best we can do for this analysis. Are the correction
factors given somewhere, or do you mean to get them by running e.g. a
certain PYTHIA tune and putting the data/PYTHIA ratios into a vector?

If the agreement is reasonably close, and there is no "official"
semi-MC-independent correction factor list, then I think it best to not
invent our own correction factors but rather to specify in the analysis
metadata that the data is uncorrected and hence should not be used in
tuning, but that it is good enough for qualitative validation comparisons.

Thanks for the effort :)
