Hanno, et al.,
We don't need numerical simulation to see that the probability around a ship's location, which is determined by two independent normal distributions of lat(x) & lon(y), is another normal distribution in the distance from the ship, r:
Prob = exp(x/s)*2 exp(y/s)*2 = exp[(x/s)*2 + (y/s)*2] = exp(r/s)*2
which, of course, is maximum at r = 0. Plot is attached with ship at 15,15.
