            <Description>4-sec vector magnetic field values recorded by the NASA ISEE-1 
satellite, in spacecraft coordinates (close to GSE), available from UCLA and CDAWeb 
value-added interfaces and, via ftp, in binary from UCLA and in CDF from 
CDAWeb. (This descriptor updated, 6/20110, by J.King, to reflect CDAWeb accessibility
and to insert CDAWeb parameter keys.)</Description>

                <Description>Data at 60-s and 4-s resolution are available for the entire ISEE mission (October 22, 1977 through  September 25, 1987) and can be displayed either as a plot or an ASCII listing. The ISEE-1 and -2 magnetometer data server is provided by the Institute of Geophysics and Planetary Physics (IGPP) at UCLA, through a grant to Robert J. Strangeway from the NASA Space Physics Data System (SPDS).</Description>
