MetadataShow full item record
A disappearance based sterile neutrino search requires knowledge of the neutrino flux at the detector. In IceCube, this this flux is provided by the interaction of cosmic rays in the atmosphere. An important property of the flux is its systematic uncertainty. This data release contains the atmospheric muon neutrino fluxes used for the IC-86 sterile neutrino analysis.
The file 'neutrino_flux_spectrums.h5' is a HDF5 dataset which contains the systematic and statistical variations of the south pole up-going atmospheric muon neutrino flux. The method used to derive this neutrino flux, and a description of the file format is provided in the included 'tech_note.pdf' document. The 'usage_example.py' file is an example python script for using the data set.
