Data Set Abstract |
These data were obtained from the LANL plasma experiment on ICE
(Principal Investigator: S.J. Bame 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
perpendicular temperature. This is done independently of the
magnetic field measurements however, the direction of maximum
temperature determined 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 sec from
the start of Day 253 (September 10) until Day 255 (September 12),
18:38. At that time the bit rate dropped from 1024 to 512 bps,
and the nominal time resolution went to 48 sec. |
