    keyword=analysis of dummy target data

    Figure 1 shows the missing energy spectrum from the dummy target.
    Upper left plot shows Em for cuts on good reactz in both spectrometers,
    as well as a cut (almost unnecessary) on good tc. tc spectrum with good
    reactz cut is shown in upper right panel, cut applied to upper left on tc
    is 160 lower left plot in fig. 1 shows the e.reactz spectrum which clearly shows the
    cell walls. lower right shows the Em plot with the same cuts as the upper
    right, but also a cut on e.reactz to exclude the cell walls:
    0.03 The prescale factors were set similarly for the dummy and prod data, so
    in the next plot I show an analysis of the production (4He) data with the
    exact same cuts, 200k espace events. conclusion: we have plenty of
    dummy target data!
