 The center of mass would be the same one as returned by the halo
 finder.  The A, B, C are the largest to smallest magnitude of the
 ellipsoid's semi-principle axes. "e0" is the largest semi-principle
-axis vector direction that would have magnitude A but normalized.  The
-"tilt" is an angle in radians. It is the rotation angle needed to align the
-medium semi-principle axis with the y axis in the x-z plane, AFTER the
-e0 axis is aligned with the x-axis in the x-y plane by rotation, then
-aligned again in the x-z plane by rotation.
+axis vector direction that would have magnitude A but normalized.  
+The "tilt" is an angle measured in radians.  It can be best described
+as after the rotation about the z-axis to allign e0 to x in the x-y
+plane, and then rotating about the y-axis to align e0 completely to
+the x-axis, the angle remaining to rotate about the x-axis to align
+both e1 to the y-axis and e2 to the z-axis.
