The following description was extracted from the
documentation files provided with the Comet P/Giacobini-Zinner
archive CDROM produced by the International Halley Watch:

These data were obtained from the LANL plasma experiment on ICE
(Principal Investigator: S.J. Bame; data provided by J.T. Gosling,
with assistance from K. Sofaly and S. Kedge). The instrument
measures the 2-D electron distribution function in one spacecraft
rotation (3 s) once every 24 s, by obtaining 16 evenly spaced
energy spectra, each with 15 contiguous levels covering the energy
range 8.5 eV to 1140 eV.   From these 2-D distributions the density,
velocity, and temperature of the electrons are then derived.  A 2-D
temperature matrix is calculated which is subsequently diagonalized.
Then nominally the maximum temperature corresponds to the parallel
temperature and the minimum temperature corresponds to the perpendi-
cular temperature. This is done independently of the magnetic field
measurements; however, the direction of maximum temperature deter-
mined in this manner is usually found to be within 15 degrees of the
magnetic field direction inferred from the magnetometer measurements.

The time resolution is 24 seconds throughout this file.

The time resolution is 24 seconds until 18:38.  At that time the
bit rate dropped from 1024 to 512 bps, and the nominal time resolu-
tion went to 48 seconds.
