Geoffrey, an example
In this example for an initial position (0N 0W) we get (No need for DR)
Ellipse:
eigenValues
0.7193
0.2770
eigenVectors
0.9844 0.1757
-0.1757 0.9844
Prob = 0.9500
k = 2.4477
theta = 10.1183
a = 1100.5655
b = 1773.4730
the big green one.
After 4 iterations:
Ellipse:
Prob = 0.9500
k = 2.4477
theta = 22.9172
a = 0.0405
b = 0.0429
The little green one
