"Figure 6 (upper left)" of "Search for $\gamma$H production and constraints on the Yukawa couplings of light quarks to the Higgs boson"

The $M_{PNet}$ distributions for the number of observed events (black markers) compared with the backgrounds estimated in the fit to the data (filled histograms) in the $b \bar b$ channel. Fail (left), medium (middle) and tight (right) regions of the $\gamma$-tagged (lower) and Untagged (upper) categories are shown. The signal contribution, stacked on top of background, is shown with an open histogram for an assumed cross section of $\sigma_{\gamma H}{\cal B}( b\bar b)=10$ fb.
