STEREO-A IMPACT (In-Situ Measurements of Particles and CME Transients) Suprathermal Ion Telescope (SIT) 1-min Level 1 Multi-Z Ion Spectra

ResourceID
spase://VSPO/NumericalData/STEREO-A/IMPACT/SIT/L1/PT1M

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.
