2.3.2 spase://NASA/NumericalData/FAST/ACF/PT5S FAST AC Fields, ~5 sec resolution FA_K0_ACF 2021-04-27T15:38:11Z FAST AC Fields Key Parameter CDF files consists of AC Electric and Magnetic fields measurements spanning a range from approximately 32 Hz to 2 MHz. The time range of each file is roughly 24 hours and consists of several passes over the auroral zone of approximately 20 minute duration, the time resolution is one spin period (approximately 5s). The orbital period of FAST is 133 minutes.
