            <Description>survey data of the DC peturbation magnetic field at 1 Hz resolution. 
                These data are for survey purposes only, they are not intended for publication or formal presentation.
                The data result from the removal of the Earth's main field and removing the spacecraft spin motion, 
                and are plotted in geomagnetic coordinates with the N-axis +ve toward magnetic north and the E-axis +ve 
                to the east. For reference, we used the system described in:
                
                Eccentric Dipole Coordinates For Magsat Data Presentation,
                D.D.Wallis, J.R. Burrows, T.J. Hughes and M.D.Wilson
                Geophysical Research Letters,
                Vol. 9 No.4, pp 353-356, April 1982.
                
                Such data are mainly useful for a qualitative assessment of the DC data and "eyeballing" interesting geophysical phenomena.
