    Re: Fix Maximum Probability Positions

    Greg,

    The attached PDF shows the error ellipses. But I use them for discussion only. From prior knowledge we know they're there, but we know little about them, and certainly not their probability structure because we've not taken statistical data under the existing navigation conditions.

    BTW, that's unlike sextant altitude measurements where many of us know our expected 1D distribution from many measurements.
