Measurement of neutrino and antineutrino oscillations by the T2K experiment, including a new additional sample of electron neutrino interactions in the far detector

September 13, 2017

This data release pertains to this paper and includes results from both the frequentist and the Bayesian analyses presented there.

Both the tar files include a README document as well as several ROOT files with the results for different oscillation parameters.

For the frequentist analysis (T2K_VALOR_Data_release), each ROOT file contains the best fit point, the 68% and 90% CL contours, the χ2 = –2 Δln(ℒ) and Δχ2 map.

For the Bayesian analysis (jointfit2016_mach3.tar), each ROOT file contains the best fit point (in 2D and 4D modes), the 68% and 90% credible intervals, the 68% and 90% contours and the posterior probability density.
