    Blessed Plots:

    The MET distribution for the data. The blue shaded histogram is the Z->nunu contribution, while the red is the total SM background. The points show the Run 1B data.
    Another plot of the MET distribution for the data. Now, only the total standard model prediction is shown. However, the size of the red box shows the uncertainty on the prediction. The points are the same as in the previous plot, showing the Run 1B data.
    ET(jet1). The data is shown by the points. The green histogram shows all backgrounds except the QCD, while the red shows the QCD predictions on top of the other backgrounds. Note that the plot of the NJet distribution almost shows the counting experiment graphically, as the predictions are condensed into two bins.
    NJet distribution. The data is shown by the points. The green histogram shows all backgrounds except the QCD, while the red shows the QCD predictions on top of the other backgrounds. Note that the NJet distribution almost shows the counting experiment graphically, as the predictions are condensed into two bins.
    ET(jet2). The data is shown by the points. The green histogram shows all backgrounds except the QCD, while the red shows the QCD predictions on top of the other backgrounds. Note that the plot of the NJet distribution almost shows the counting experiment graphically, as the predictions are condensed into two bins.
    DeltaPhi(min) between the jets and MET. In all four plots, the data is shown by the points. The green histogram shows all backgrounds except the QCD, while the red shows the QCD predictions on top of the other backgrounds.
    Missing ET distribution for the data. The points show the data and the shaded histogram shows the predicted standard model backgrounds. Note that this is the same as the first plot. On top of this, the unshaded histogram shows the expected contribution for a signal for MD=1 TeV and n=2.
    ET(jet1). The points show the data and the shaded histogram shows the predicted standard model backgrounds. On top of this, the unshaded histogram shows the expected contribution for a signal for MD=1 TeV and n=2.
    NJet distribution. The points show the data and the shaded histogram shows the predicted standard model backgrounds. On top of this, the unshaded histogram shows the expected contribution for a signal for MD=1 TeV and n=2. Note again that the NJet distribution almost shows the counting experiment graphically, as the predictions are condensed into two bins.
    ET(jet2). The points show the data and the shaded histogram shows the predicted standard model backgrounds. On top of this, the unshaded histogram shows the expected contribution for a signal for MD=1 TeV and n=2.
    DeltaPhi(min) between the jets and MET. The points show the data and the shaded histogram shows the predicted standard model backgrounds. On top of this, the unshaded histogram shows the expected contribution for a signal for MD=1 TeV and n=2.
