Three-year high-statistics neutrino oscillation samples


In 2013, IceCube reported its first measurement of the neutrino oscillation parameters. This was the first time that neutrino oscillations were measured with precision at energies above 10 GeV. A year later, the collaboration presented a second analysis with three years of data that improved the precision by a factor of ten. The IceCube Collaboration has now published in Physical Review Letters [1] and Physical Review D [2] new measurements of neutrino oscillation using atmospheric neutrinos from the full sky with reconstructed energies between 5.6 and 56 GeV. Two separate event selections and analyses (A & B) were used and made available here.

Data files

The archive file contains two dataset samples. These two samples are not independent, and analyses must not combine the samples or results obtained thereof in any way.

Sample A is used for the primary nutau appearance result [2], and is used in the first IceCube neutrino mass ordering analysis [3].

Sample B is an updated version of what is used for the primary IceCube muon neutrino disappearance measurement [1], with chi2 maps made available here. Sample B also serves as the confirmatory analysis in [2] and is used in [3].

Both samples are described in detail in reference [2] and the provided download contains a readme.txt for both samples which contains a more detailed overview of each data file.
