[Rivet] CMS_2013_I1122847 (Forward-backward asymmetry in DY)

[Albert Knutsson]

Dear Holger,

The predictions in the paper are POWHEG+PYTHIA6. The predictions in the 
validation plots are POWHEG+PYTHIA8 (as the file name of the validation 
plots I sent indicate). Both of the predictions are describing the data 
within the uncertainties of the data.

It is already written in the info-file that QED radiation for the 
leptons should be turned off. I added the the word born level now. New 
tar-ball attached.

Thanks and cheers,
Albert
