Description

This data sets contains MMS-3 SCM (search coil magnetometer) calibrated power spectral density of Magnetic field fluctuations computed by onboard FFTs by the Digital Signal Processor (DSP) from SCM waveforms during slow survey modes between 0 and 8192 Hz. Their nominal time resolution is 16 s, and nominal number of frequency channels is 56 with logarithmic frequency scale.
This product is computed in space from individual components that are not synchronized to the 1 second pulse. Therefore, the timing between channels can be inaccurate by a fraction of a second. The samples times are interval start times taken from the x component.
- SCM1 (spin plane component, -x SCM sensor) component magnetic power spectral density.
- SCM3 (spin axis component, -y SCM sensor) component magnetic power spectral density.
- Omni-directional magnetic power spectral density: square root of the sum of the squares of 2 components (SCM1 and SCM3).
