      <ResourceName>STEREO-B IMPACT (In-Situ Measurements of Particles and CME Transients) Suprathermal Ion Telescope (SIT)1-min Level 1 Multi-Z Ion Spectra</ResourceName>
      <ReleaseDate>2021-04-27T15:38:11Z</ReleaseDate>
      <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.</Description>
