This data set, on one reel each of 35-mm and 16-mm microfilm made at NSSDC from Calcomp plots generated at UCLA, contains 2.5-min-averaged, machine-corrected, reduced magnetometer data presented in the UCLA/ATS dipole VDH coordinate system (described below). Plotted against a common time axis are the three magnetic field Cartesian components, labelled V, D, and H, and an indicator of the satellite state descriptor, labelled S. The plotted value of S is a binary code for the status of various significant spacecraft subsystems, which is useful in identifying offset changes that are not corrected by machine in the plotted data. The spacecraft state descriptor has also been referred to as the spacecraft state vector. The UCLA/ATS dipole VDH coordinate system has the H axis antiparallel to the earth's magnetic dipole axis, the V axis radially outward in the magnetic equatorial plane, and the D axis azimuthally eastward.
