Updated measurements of muon neutrino and antineutrino disappearance
This data release pertains to this paper.
The tar file for this data release includes a README document as well as a ROOT file.
The ROOT file contains the best fit point, the $\chi^{2}=-2 \Delta \ln \mathcal{L}$ distribution, and the contours that define the 68\% and 90\% confidence regions in the $\sin^2 \theta_{23}$ Vs $\Delta m^2_{32}$ plane. All those results correspond to the simultaneous fit of the 1 ring muon-like events recorded during neutrino and antineutrino running modes. The results are given separately for the parameters describing the disappearance of muon neutrinos and of muon antineutrinos, and are provided for the normal and inverted mass hierarchy cases.

Neutrino beam flux prediction 2016
The files in the following archive file contain the neutrino and antineutrino beam flux predictions for the T2K ND280 (near) and Super-Kamiokande (far) detectors. It supersedes the previous flux release in 2013.
The original description of the flux predictions is published in this paper. Since the publication, the flux prediction has been updated with new thin target data from the NA61/SHINE experiment, and flux predictions for antineutrino enhanced beam operation have been produced. The NA61/SHINE thin target measurements of π±, K±, KS0, Λ and p production are published in Eur. Phys. J. C (2016) 76:84. The updated flux prediction is described in Phys. Rev. D 91, 072010 (2015).
The provided flux predictions include no neutrino oscillations.
This tar file contains the flux predictions as well as a README.pdf file with detailed information on the included files:
