The data comprise exposures of 10.71×1020 protons on target in the ?µ-dominated beam, 3.36×1020 protons on target in the ?¯µ-enhanced beam, and 37.88 kton yr of atmospheric neutrinos. Assuming identical ? and ?¯ oscillation parameters, we measure |?m2|=(2.41-0.10+0.09)×10-3 eV2 and sinâ¡2(2?)=0.950-0.036+0.035. Allowing independent ? and ?¯ oscillations, we measure antineutrino parameters of |?m¯2|=(2.50-0.25+0.23)×10-3 eV2 and sinâ¡2(2?¯)=0.97-0.08+0.03, with minimal change to the neutrino parameters.
