The calculations are based on CT18NNLO parton distribution functions, and their uncertainties. For the highest energies, we extrapolate the PDFs to small x according to several assumptions, which affect the uncertainties at such high energies.
The results can be applied to astrophysical neutrino observatories, such as IceCube currently and proposed future detectors.
