Assuming no error in the true position announced by Tom Cruise (presumably from a GPS) the distribution should look like those in appendix Q of Bowditch. http://fer3.com/arc/imgx/HO-9-1977-Appendix-Q.pdf http://fer3.com/arc/imgx/Figure-Q6d_0001.pdf http://fer3.com/arc/img/114399.extended%20table%20q7d.pdf http://fer3.com/arc/m2.aspx/Accuracy-sextant-observations-sea-LaPook-nov-2010-g14399 If it is a two body fix with the LOPs crossing at 90° it should be a circle and if they cross at a different angle then it should be an ellipse. The size of the ellipse (or circle) will be based on the average standard deviation of the observers. gl --- On Tue, 3/12/13, Hanno Ix <hannoix@att.net> wrote:
