4.608-Sec Averaged Fluxgate Magnetometer Data in Spacecraft Coordinates

Description

This magnetic field data set is on experimenter-supplied, binary magnetic tapes generated on an IBM 360/91 computer. Each tape contains data files with a header and trailer file for each data file. Each file contains overlapping data into the next orbit at perigee. As offset corrections are introduced at apogee and extrapolated backward and forward in time throughout each orbit, these overlapping periods in general will not exactly agree. Each physical record contains 128 logical records of six words each. Each logical record contains Bishop time (10ths of seconds since January 1, 1966), the vector magnetic field as averaged over 4.608 s in spacecraft coordinates, the total field magnitude, and a quality indicator. Offset corrections will have to be applied to these data to obtain accuracy in absolute magnitudes of better than 10 nT, but relative changes are reliable to 0.128 nT per component.
