Description

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.

Name

Magnetic field spectral density

Description

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).

Caveats

Data records actually contain sensor output voltages and conversion factors for transforming to spectral densities.
