Table 6.

The pythia8 parameters, tuning ranges, Tune 4C values [28] and best-fit values of CDPSTP8S1-Wj and CDPSTP8S2-Wj, obtained from fits to DPS observables in W+dijet production with the MadGraph event generator interfaced to pythia8. Also shown are the predicted values of σeff at s=7TeV, and the uncertainties obtained from the eigentunes
