This magnetic field data set is on six experimenter-supplied, 7-track, 556-bpi, BCD magnetic tapes. Information related to a single observation occupies three 112-character records. Two of these records contain 10-s averages of eight magnetic field items presented every 5 min. These items, derived from the orthogonal component measurements, are the right ascension, declination, and magnitude of the field, the polar angle of the field vector (measured relative to the satellite spin axis), the azimuthal angle of the field vector (measured relative to the satellite meridian plane passing through the sun), and the standard deviation of each of the three Cartesian components. The third record contains the following: day number (from day of launch); hour, minute, millisecond; geocentric longitude, latitude, and radius; McIlain's L parameter; and the theoretical field magnitude based on the 1962 model of Jensen and Cain. These data are time ordered and cover approximately 70% of the period from January 1, 1963, to May 30, 1963. Many of the data gaps are due to perigee passing (magnitude of the magnetic field is greater than 500 nT), and these occur with a period of approximately 36.4 h.
