The ephemeris data is at 5 min resolution. The files include the magnetic coordinates, spacecraft radial locaton, the L shell information, the spacecraft position in ECI coordinates, and the northern and southern hemisphere foot print location in geographic latitutde and longitude coordinates at 100 km in altitude.
