Fig. 3. Fitted event distributions and ratios in the control regions.

Fitted event distribution in the calculated Q² ($Q_{\mathrm{QE}}^2$) bins in the QELike sample in the QE, non-QE, as well as non-QE and mesons, regions. Top, event rate per bin; Bottom, ratio to post-fit model. The vertical error bars around the data points and the error band around the model prediction account for 1 standard deviation due to large statistical uncertainties.
