Comparison of nominal IAU Titan spin axis and several versions of the estimated north pole of Titan. The pole was estimated using 14, 50, and 151 features. The resultant estimated locations (three red symbols) are tightly grouped together, especially when compared to the nominal location (green cross). Because the IAU Titan spin model was developed with a presumption of zero obliquity the IAU Titan spin axis is the same as the orbit normal. All four pole locations depicted are at time 19:16:25 UTC Aug 1 2006.
