+      <Description>The coordinate resolution for the magnetic field components is the
+I,S coordinate system, defined by the JPL group before launch.  I is
+the unit vector in the direction of the ICE spin axis (positive in
+the northward direction), and S is the unit vector from the space-
+craft to the Sun.  The Z-axis ia equal to I, the Y-axis to the nor-
+malized cross-product I x S, and the x-axis to Y x Z.  The I,S co-
+ordinate system us approximately the same as the Solar Ecliptic (SE)
+system since the spacecraft Z-axis is maintained within half a degree
+of perpendicular to the Ecliptic plane.  (SE is defined the same way
+as GSE, but with the spacecraft [point of observation] substituted
+for Earth). </Description>
