A variation-based analysis shows that constraining atmospheric muon flux with precision data can reduce sub-GeV atmospheric neutrino flux uncertainty, most effectively when muons are measured at 3000-5000 m altitude sites.

abstract
Atmospheric neutrino-fluxes are calculated over the wide energy range from 30 MeV to 3,000 GeV for the study of neutrino-physics using the data from underground neutrino-detectors. The atmospheric muon-flux at high altitude and at sea level is studied to calibrate the neutrino-fluxes at low energies and high energies respectively. The agreement of our calculation with observations is satisfactory. The uncertainty of atmospheric neutrino-fluxes is also studied.

Reduction of the Uncertainty in the Atmospheric Neutrino Flux Prediction Below 1 GeV Using Accurately Measured Atmospheric Muon Flux
A variation-based analysis shows that constraining atmospheric muon flux with precision data can reduce sub-GeV atmospheric neutrino flux uncertainty, most effectively when muons are measured at 3000-5000 m altitude sites.
