2.2.2 spase://VSPO/NumericalData/FAST/DCF/KP/PT5S FAST DCF Key Parameters 2011-09-14T00:00:00.000Z This data set provides the 5-second (spin-averaged) FAST survey electric and magnetic field (Delta B) 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. spase://SMWG/Person/Charles.W.Carlson PrincipalInvestigator FAST Documentation http://sprg.ssl.berkeley.edu/fast/scienceops/fastdocs.html spase://SMWG/Repository/NASA/GSFC/SPDF Online Open SPDF FTP area ftp://spdf.gsfc.nasa.gov/pub/data/fast/dcf/dcf_k0/ In CDF via FTP from CDAWeb SPDF HTTP area http://spdf.gsfc.nasa.gov/pub/data/fast/dcf/dcf_k0/ In CDF via HTTP from CDAWeb CDF spase://SMWG/Repository/NASA/GSFC/SPDF Online Open CDAWeb http://cdaweb.gsfc.nasa.gov/sp_phys/ FA_K0_DCF Plots, lists, and data from CDAWeb.
