Fig. 1
Δtobs/(1 + z) versus K plot for TeV neutrino events. The black triangles are experimentally measured data, and the red lines are linear fits to experimental data. All nine events fall near a pair of lines noted as a and b. The different signs of slopes may be the result of intrinsic distinctions between neutrino and anti-neutrino. The error bars are calculated according to uncertainties of energy, red-shift and cosmological parameters (see Methods)
