      <ResourceName>ISEE 1 VES Electron Data at 9s or 18s</ResourceName>
      <ReleaseDate>2021-04-27T15:38:11Z</ReleaseDate>
      <Description>This data set, held in CDAWeb as ISEE1_H0_FE,
contains electron moments from the Vector Electron Spectrometer
(VES), and spacecraft position vectors, at 9s or 18s resolution, 
depending on spacecraft telemetry rate.  The data set
also holds 1-min averages of the measured magnetic field
vector.  Electron moments include density, flow velocity,
temperature and its anisotropy, and heat flux vector.  Also given
are the pressure tensor, its diagonalizing eigenvector, and the 
angle between its principal axis and the ambient magnetic field 
vector.  These parameters are based on distributions accumulated
in 3 sec but telemetered over 9s or 18s.  Ancillary information 
given includes the spacecraft spin period, the spacecraft 
potential, the energy channels above this potential on which the 
moments for this record were based, and on/off flags for the 
Harvey and Mozer experiments.</Description>
