90% C.L. allowed regions of and oscillation parameters from atmospheric neutrino [32] and long baseline [38, 55] neutrino oscillation experiments with 2-flavor oscillation assumption. For atmospheric neutrinos, results from the zenith angle and analyses are plotted. Also shown is the allowed region on these parameters from the full 3-flavor analysis of the Super-K atmospheric neutrino data. For 3-flavor oscillations, normal mass hierarchy and the best fit are assumed.
