Start:1996-08-30 00:00:00 Observatory:FAST Cadence:5 seconds

This data set provides the 5-second (spin-averaged) FAST survey electric and magnetic field data within the low altitude auroral arc region. The three-axis searchcoil magnetometer (the AC magnetometer) provides measurement of structures and waves corresponding to ELF and VLF frequencies. Magnetic field power spectral densities are obtained between 10 Hz and 4 kHz on two axes, and from the third one that is sampled up to 2 MHz, the magnetic component of auroral kilometric radiation (AKR). Once the auroral electron precipitation is detected, survey data will shift from a slow to a fast survey mode at rates of 32 to 2048 samples per second. Slow survey data has ~0.06 s resolution, and fast survey, typically has ~0.5 ms resolution. There is a frequency-dependent sensitivity between 10^-8 and 10^-10 nT^2/Hz. Electric field power spectral densities are also provided for the same frequency ranges.

Stop:2009-04-30 10:22:28 Instrument:Electro-Static Analyzers (ESA) Resource:NumericalData
This data set provides the electron part of the 5-second (spin-averaged) FAST survey data from the Electrostatic Analysers (ESA) instrument in CDF format. It includes: the electron energy fluxes for 47 energies (4eV-30keV) in the pitch angle ranges 0-30, 60-120, and 150-180; the electron energy fluxes for 32 pitch angles (-90 to 270 deg) in the energy ranges 0.1-1keV and 1-30keV; the integrated electron energy (and number) fluxes mapped to the magnetic foot point; and orbit information. Data are derived from a pair of hemisperical electrostatic analyzers with 180 degree radial FOVs that together form a single 360 deg x 4.5 deg planar FOV in the spin spacecraft plane. Sensors can deflect their FOV by up to +/-10 deg to follow the magnetic field direction which is within +/-6 deg of the spin plane for most auroral crossings. Absolute geometric factors are the best estimate at the time of key parameter data production (20% uncertainty). Key parameter data are averaged for 1 spin. Any change in sensor configuration or onboard data storage during a spin result in a rejection of the spin average. More specifically, Electron Sensor Parameters include: Inner Hemisphere R = 3.75 cm; dR/R = 0.06; FOV = 360 deg x 4.5 (FWHM) deg; Angular resolution = 11.25 deg x 4.5 deg; Energy range: 4 eV to 30 keV; dE/E = 0.15 (FWHM); and Geometric Factor = 0.0047 x E (cm2-sr-eV) Key Parameter Data include: Electron Energy-Time Spectrogram, 0-30 deg pitch angle; Electron Energy-Time Spectrogram, 60-120 deg pitch angle; Electron Energy-Time Spectrogram, 150-180 deg pitch angle; Electron Pitch Angle-Time Spectrogram, 0.1-1.0 keV; Electron Pitch Angle-Time Spectrogram, 1.0-30.0 keV; Electron Energy Flux mapped along B to 100 km altitude; and Electron Number Flux mapped along B to 100 km altitude.

Resource ID:spase://VSPO/NumericalData/FAST/TMS/KP/PT5S
Start:1996-10-01 00:00:00 Observatory:FAST Cadence:5 seconds
Stop:2009-04-30 10:22:16 Instrument:Time of Flight Energy Angle Mass Spectrograph Resource:NumericalData
The data set provides the 5-second (spin-averaged) FAST survey data from the Time of flight Energy Angle Mass Spectrograph (TEAMS) in CDF format. The data set includes H+, O+, and He+ differential energy fluxes. Pitch-angle-averaged fluxes are provided for 48 energies (1eV-12keV). Energy-averaged fluxes are provided for 16 pitch angles (0-360 deg) for the energy range 0.01-1keV and >1keV. Each angle segment contains 2 (4) samples at each energy in the 32 (64) sweep/spin mode. The full angular range is covered in half a spin but the actual time resolution of the survey data product depends upon the telemetry mode. In the highest TM rate modes H+ and O+ survey data read out every half spin. In lowest TM rate mode these data are accumulated for 4 spins. The minimum accumulation time included in the CDF is 1 spin, so if the actual accumulation time is a half spin, two data points are averaged. Otherwise, the full resolution is included. In every mode He+ and He++ are accumulated twice as long as H+ and O+. To force the H+, O+, and He+ to have an equal number of data points when H+ and O+ have twice the time resolution, each He+ data point is written twice consecutively in the file. Orbit parameters are also included in this data set.
