Antiproton Flux, Antiproton-to-Proton Flux Ratio, and Properties of Elementary Particle Fluxes in Primary Cosmic Rays Measured with the Alpha Magnetic Spectrometer on the International Space Station

The antiproton flux $\Phi^{\bar p}$ and the antiproton/proton flux ratio $\Phi^{\bar p}/\Phi^{p}$ as a function of absolute rigidity at the top of AMS. $\tilde{N}^{\bar p}$ is the number of antiprotons observed in each rigidity bin rounded to the nearest integer. $\sigma_{\rm stat}$ and $\sigma_{\rm syst}$ are the respective statistical and systematic errors.

The antiproton-to-positron flux ratio $\Phi^{\bar p}/\Phi^{e^+}$ and the antiproton-to-electron flux ratio $\Phi^{\bar p}/\Phi^{e^-}$ as a function of rigidity at the top of AMS. $\sigma_{\rm stat}$ are the statistical errors on the ratios, $\sigma_{\rm syst}$ are the systematic errors on the ratios, and $\sigma_{\rm scale}$ are the errors from the energy scale uncertainty in $\Phi^{e^\pm}$. The antiproton flux binning is used.
