This magnetometer data set is on an experimenter-generated, BCD magnetic tape, with 80 characters per logical record, and 3204 characters per physical record. The tape contains time, the spacecraft state descriptor, and 2.5-min averaged Cartesian magnetic field components in the UCLA/ATS dipole VDH coordinate system, described below. The spacecraft state descriptor contains three groups of eight hexadecimal characters. When these are expanded into a binary number, the succesive bits represent on-off states of the various subsystems as well as the order in which some of these were turned on. The spacecraft state descriptor has also been referred to as the spacecraft state vector. These data have been corrected for offsets by machine as much as possible. They still contain some offset errors, but consideration of the spacecraft state descriptor allows correction for these by hand. 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.
These data are available at: https://spdf.gsfc.nasa.gov/pub/data/ats/ats1/biaxial_fluxgate_magnetometer/ in the directory /2.5_min_avg_vect_mag_field/.
