Aureol 3 VLF Data

For any given time segment the power for any one of five predefined pairs of the five measurable field components (EZ, EH, BZ, BX, BX45) were measured and are included. The components of electromagnetic field are named by their direction in the satellite frame.

Spacecraft position in geographic and magnetic coordinates are also included, along with time and an indication of which pair of components were measured. Each data file corresponds to one memory readout, and typically consists of a few continuous-data segments. The first several records in each file constitute a header giving the time spans of the segments, the time resolution, and other common information.
