        "Description": "PSP FIELDS Fluxgate Magnetometer data. Time resolution varies with instrument mode, ranging from 2.3-292.9 samples/sec, corresponding to 2-256 samples per 0.874 seconds (0.874 = 2^25 / 38.4 MHz, see reference [2]).The Magnetometer has 4 ranges - +/-1024, +/-4096, +/-16,384, +/-65,536 nT, selected by the ranging algorithm, based on the ambient magnetic field. Precision is +/- 15 bits, based on the 16-bit ADC.References:1. Fox, N.J., Velli, M.C., Bale, S.D. et al. Space Sci Rev (2016) 204: 7. https://doi.org/10.1007/s11214-015-0211-62.
