Coverage caveats the paper itself states: no direct flux measurements exist for nuclei heavier than the iron-nickel group above ~10 GeV/nucleon, so gold-and-up fluxes at 100 GeV-20 TeV/nucleon are extrapolations resting on (a) the universal measured power law (verified for H, He, O, Mg, Si, Fe) and (b) abundance ratios tracking solar-system values wherever measured; the conservative choices gamma = 2.7 and Gamma(Au)/Gamma(Fe) = 1e-5 (estimates range to 1e-4) are used. The spectral knee at 1e15 eV lies above the energies used.
