      <Description>

         Solar Wind Ion parameters from ACE/SWEPAM. Level 2 data, 64-second averages (from AC_H0_SWE dataset). Parameters include proton density, 
         temperature (radial component) and flow speed, flow velocity vector in GSE and GSM coordinates, and alpha 
         to proton density ratio.        
         AMDA presents temperature in eV.

   <Caveats>
      The quality of ACE level 2 data is such that it is suitable for serious scientific study. However, to avoid confusion and misunderstanding, it is recommended that users consult with the appropriate ACE team members before publishing work derived from the data. The ACE team has worked hard to ensure that the level 2 data are free from errors, but the team cannot accept responsibility for erroneous data, or for misunderstandings about how the data may be used. This is especially true if the appropriate ACE team members are not consulted before publication. At the very least, preprints should be forwarded to the ACE team before publication.
