Description
The IMPACT Suprathermal Ion Telescope (SIT) data consist of 1-min resolution ion fluxes of the following species (and numbers of energy bands, typically spanning ~0.04-9 MeV/n): H(12), 3He(10), 4He(16), C(17), O(16), NeS(16; neon through sulfur), Fe(14), UH(6; ultra heavy; 0.06-0.5 MeV/n), and associated uncertainties due to counting statistics.
