THEMIS-B: ESA electron/ion energy fluxes and moments

ResourceID
spase://NASA/NumericalData/THEMIS/B/ESA/PT3S

Description

THEMIS-B: Electrostatic Analyzers (ESA): Electron/Ion Ground-Calculated Energy Fluxes (5eV - 25 keV for Ions and 6eV - 30 KeV for Electrons) and Moments (density, velocity, pressure, and temperature). The satellite has 2 modes Fast and Slow survey and 3 data types: FULL, REDUCED and BURST. FULL: 88 angles x 32 energies, time resolution of 128 spins(395 seconds) in slow survey and 32 spins(98 seconds) in fast survey. REDUCED: spin time resolution(3 sec) but angles averaged into 1 angular spectra x 32 energies in slow survey or 6 angular spectra(90 degree x 90 degree window) x 32 energies in fast survey. BURST: 88 angles x 32 energies and spin time resolution(3 sec) but only available sporadically and for short duration. Note that angular resolution affects moments since they are obtained integrating over the mode-specific angular distribution. These moments are processed on the ground. They should be regarded as approximations but will improve in quality as our processing routines are improved over the course of the mission to account for additional sources of variance.

Caveats
See THEMIS website for caveats(http://themis.ssl.berkeley.edu) EFI booms for THEMIS B(P1) were deployed on 2007-11-17/06:00:00 UT. Before this time the spacecraft potential was not calculated accurately. Electron moments will not be distributed prior to this date and ion moments will less accurate.

Description

The Spacecraft Potential that was used for calculating the moments that were generated from the full angle distribution. This parameter was taken from the efi data and interpolated to the cadence of the esa full distribution data.

Caveats
This spacecraft potential parameter is the current best estimate of the spacecraft potential, estimates will improve as the mission continues. Some of the data are at a cadence of 395 seconds, cadences switch due to mode changes on the probe. EFI booms for THEMIS B(P1) were deployed on 2007-11-17/06:00:00 UT. Before this time this spacecraft potential was not calculated accurately.

Description

Ion temperature eigenvalues of the diagonalized pressure tensor calculated from the full angle distribution. Includes two perpendicular elements and one parallel element. (Tprp1_ion, Tprp2_ion, Tpar_ion)

Caveats
The first eigenvalue and eigenvector are the distinguisheable eigenvalue and the major (symmetry) axis, respectively. .The "degenerate" eigenvalues are sorted such that the 2nd eigenvalue is smaller than the third one. Coordinate system is ostensibly magnetic field aligned but may deviate if the particle distribution is strongly isotropic. Some of the data are at a cadence of 395 seconds, cadences switch due to mode changes on the probe.

Parameter #28
Name
Electron Diagonalized Temperature
ParameterKey
thb_peef_t3
Description

Electron temperature eigenvalues of the diagonalized pressure tensor calculated from the full angle distribution. Includes two perpendicular elements and one parallel element. (Tprp1_elec, Tprp2_elec, Tpar_elec)

Caveats
The first eigenvalue and eigenvector are the distinguisheable eigenvalue and the major (symmetry) axis, respectively. .The "degenerate" eigenvalues are sorted such that the 2nd eigenvalue is smaller than the third one. Coordinate system is ostensibly magnetic field aligned but may deviate if the particle distribution is strongly isotropic. Some of the data are at a cadence of 395 seconds, cadences switch due to mode changes on the probe.

Ion Diagonalized Temperature: reduced angle distribution
ParameterKey
thb_peir_t3
Description

Ion temperature eigenvalues of the diagonalized pressure tensor calculated from the reduced angle distribution. Includes two perpendicular elements and one parallel element. (Tprp1_ion, Tprp2_ion, Tpar_ion)

Caveats
The first eigenvalue and eigenvector are the distinguisheable eigenvalue and the major (symmetry) axis, respectively. .The "degenerate" eigenvalues are sorted such that the 2nd eigenvalue is smaller than the third one. Coordinate system is ostensibly magnetic field aligned but may deviate if the particle distribution is strongly isotropic. Data are produced from distributions that are reduced by averaging over angles. In slow survey mode a single angular bin is used. In fast survey six 90 degree by 90 degree bins are used.

ESA Electron energy spectrogram energy flux calculated from reduced angle distribution.

Caveats
Energy levels of eflux bins are stored in thb_peer_en_eflux_yaxis. Data are produced from distributions that are reduced by averaging over angles. In slow survey mode a single angular bin is used. In fast survey six 90 degree by 90 degree bins are used.

Electron Diagonalized Temperature: reduced angle distribution
ParameterKey
thb_peer_t3
Description

Electron temperature eigenvalues of the diagonalized pressure tensor calculated from the reduced angle distribution. Includes two perpendicular elements and one parallel element. (Tprp1_elec, Tprp2_elec, Tpar_elec)

Caveats
The first eigenvalue and eigenvector are the distinguisheable eigenvalue and the major (symmetry) axis, respectively. .The "degenerate" eigenvalues are sorted such that the 2nd eigenvalue is smaller than the third one. Coordinate system is ostensibly magnetic field aligned but may deviate if the particle distribution is strongly isotropic. Data are produced from distributions that are reduced by averaging over angles. In slow survey mode a single angular bin is used. In fast survey six 90 degree by 90 degree bins are used. This quantity will not be available before the THEMIS B(P1) efi boom deployment date: 2007-11-17/06:00:00 UT.

Ion Diagonalized Temperature: burst angle distribution
ParameterKey
thb_peib_t3
Description

Ion temperature eigenvalues of the diagonalized pressure tensor calculated from the burst angle distribution. Includes two perpendicular elements and one parallel element. (Tprp1_ion, Tprp2_ion, Tpar_ion)

Caveats
The first eigenvalue and eigenvector are the distinguisheable eigenvalue and the major (symmetry) axis, respectively. .The "degenerate" eigenvalues are sorted such that the 2nd eigenvalue is smaller than the third one. Coordinate system is ostensibly magnetic field aligned but may deviate if the particle distribution is strongly isotropic. Burst distribution is used to generate these quantities. It is available at high temporal(3s/1spin) resolution and high angular resolution(88 angles), but it is only available very infrequently.

Name
Electron Diagonalized Temperature: burst angle distribution
ParameterKey
thb_peeb_t3
Description

Electron temperature eigenvalues of the diagonalized pressure tensor calculated from the burst angle distribution. Includes two perpendicular elements and one parallel element. (Tprp1_elec, Tprp2_elec, Tpar_elec)

Caveats
The first eigenvalue and eigenvector are the distinguisheable eigenvalue and the major (symmetry) axis, respectively. .The "degenerate" eigenvalues are sorted such that the 2nd eigenvalue is smaller than the third one. Coordinate system is ostensibly magnetic field aligned but may deviate if the particle distribution is strongly isotropic. Burst distribution is used to generate these quantities. It is available at high temporal(3s/1spin) resolution and high angular resolution(88 angles), but it is only available very infrequently. This quantity will not be available before the THEMIS B(P1) efi boom deployment date: 2007-11-17/06:00:00 UT.
