Caption: The kinematic coverage of the data used in the neutral kaon production cross section fit. The plot shows the υK versus PK values for the E910 and Abe et al. data for neutral kaon production by incident protons on a Be target. The E910 experiment used beam protons with a momentum of 12.3 or 17.6 GeV/c and the Abe et al. experiment used a 12.0 GeV/c incident proton beam. The scatter plot gives the kinematic region for kaons that produces electron neutrinos in MiniBooNE detector.
