<Description>
HYDRA is a 3-Dimensional Electron and Ion Hot Plasma Instrument for
the Polar Spacecraft of the GGS Mission ( J. Scudder et al., Space Sci. Rev.,
71,459-495, Feb. 1995. http://www-st.physics.uiowa.edu ).
This data set contains
survey electron and proton moments for the energy flux (parallel), at
13.8-second resolution as determined ( 0-20 keV ). Higher quality data products may
be available from the P.I.
