Pioneer 10/11 data analysis of the magnetic field experiment

Work conducted in support of the Pioneer missions to Jupiter (10,11), and Saturn (11) as well as the reduction, analysis and interpretation of magnetic field data obtained by the vector helium magnetometer on the Pioneer 10 and 11 spacecraft is summarized. Initial efforts concentrated primarily on the interplanetary data, and those aspcts of the data of relevance to obtaining a better understanding of the interaction of the magnetized solar wind with the terrestrial magnetic field. After encounters of Jupiter and Saturn, the emphasis of research was directed primarily to an analysis of the planetary data. In particular, it soon became clear that there was a need for modelling of the various candidate magnetospheric currents suggested by the data. Results not published as yet, are also summarized.
