Preliminary results Summary of early results from Explorer 12 (R22.1)
Measured data (k, w, Bo, E(t), B(t), polarisation, Vphase, ...) The field magnitude and its standard deviation, the polar angle of the field vector
(measured relative to the satellite spin axis) and its standard deviation,
and the azimuthal angle of the field vector (measured relative to the satellite meridian plane
passing through the sun) and its standard deviation.
