Figure 2.Zenith-angle (?) distribution of neutrinos observed at the Super-Kamiokande detector over a period of 535 days. The cross-bars show number of events observed in each range of value of cos ?, with the horizontal bars indicating the extent of the range and the vertical bars indicating the statistical uncertainty in the frequency of the neutrinos. Rectangles show the expected number of events predicted by a theoretical calculation; the thickness of the rectangles shows the range of uncertainty of the prediction. (a) Electron neutrinos. (b) Muon neutrinos.
