"Figure 6a" of "Measurement of inclusive and differential cross sections for single top quark production in association with a W boson in proton-proton collisions at $\sqrt{s}$ = 13 TeV"

The distribution of the BDT discriminant for events in the 1j1b region. The data (points) and the MC predictions (coloured histograms) after the fit are shown. The vertical bars on the points represent the statistical uncertainty in the data, and the hatched band the total uncertainty in the MC prediction. The lower panels display the ratio of the data to the sum of the MC (points) predictions after the fit, with the bands giving the corresponding uncertainties.
