Each prediction is normalised to the correct data POT/livetime so as to allow direct comparison. When using the predictions, note that the components use a naming convention that is {original flavor}{oscillated flavor}Comp , with the flavours being M (muon neutrino), AM (muon antineutrino), E (electron neutrino), AE (electron …",
