2.2.2 spase://NASA/NumericalData/Helios1/E4/PT8S Helios 1 Magnetic Field Spectral Density, offline at NSSDC 2021-03-11T18:39:11Z This data set contains 8-sec averaged and peak spectral densities of magnetic field component variations in 8 spectral bands with center frequencies logarithmically equispaced between 6.8 Hz and 1470 Hz. Data records also contain time, spacecraft position, spacecraft-sun-Earth angle, spin vector direction, data quality flags, etc. Please acknowledge the PI, Dr. Fritz Neubauer, and NSSDC. spase://SMWG/Person/Fritz.M.Neubauer PrincipalInvestigator FTPS from SPDF (not with most browsers) https://spdf.gsfc.nasa.gov/pub/documents/old/documentation_from_nssdc/dataset_catalogs/DSC_0506.pdf spase://VSPO/NumericalData/SPHE_00177 spase://VSPO/NumericalData/Helios1/E4/PT8S spase://SMWG/Repository/NASA/GSFC/SPDF Offline Open NSSDC https://nssdc.gsfc.nasa.gov/nssdc/obtaining_data.html Binary 600 MB Uncalibrated spase://SMWG/Instrument/Helios1/E4 MagneticField Spectrum 1974-12-10T00:00:00 1975-09-20T00:00:00 PT8S Heliosphere.Inner Magnetic field spectral density Eight spectral densities for each of two field components (the spin-aligned component and one of the normal-to-spin-vector components) for either mean values or peak values (determined by flag set elsewhere in data record). Data records actually contain sensor output voltages and conversion factors for transforming to spectral densities.
