Fcp = Fce/1837 in kHz. FcO+ = Fcp/16 in kHz. All frequencies in the key parameters are converted to Hz.Since the SFR frequency steps vary with the mode, the measured SFR frequencies will be mapped to a fixed array of 160 approximately logarithmically spaced frequency values, 32 frequency values for each of the five SFR channels. In the log mode, the 64 frequency steps of the fourth and fifth frequency channels will be mapped to 32 frequency steps each, using geometric averaging. In the linear mode, the 448 linearly spaced frequency steps of the five frequency channels will be mapped to the fixed array of 160 logarithmically spaced frequency values using a windowing technique. The magnetic and electric field values corresponding to each SFR frequency step will be similarly mapped to 160-point fixed arrays corresponding to the mapped frequency array. <_Description>Source: Master/CDFglobalAttributes/TEXT <_Rights> SPDX Creative Commons Zero v1.0 Universal https://spdx.org/licenses/CC0-1.0.html https://spdx.org/licenses/ POLAR PWI KPGS https://doi.org/10.48322/0zmq-1b63 <_DOI>Source: https://github.com/rweigel/cdawmeta-spase/blob/main/DOI.json <_AccessInformation>Source: https://github.com/rweigel/cdawmeta-spase/blob/main/AccessInformation.json 1996-02-27T12:20:27Z 1997-09-16T16:51:41Z <_TemporalDescription>Generated from all.xml/@timerange_start and all.xml/@timerange_stop PT4M59S <_Cadence>Counts based on variable 'Epoch' in https://cdaweb.gsfc.nasa.gov/sp_phys/data/polar/pwi/pwi_k0/1996/po_k0_pwi_19960227_v02.cdf.
