    Taking more sights for one star when triangle not equilateral

    Thanks for the sights you shared especially Dave Pike.
    Suppose you have only three celestial bodies at rather unfavourable
    angles, ie a non- equilateral cocked hat. And suppose due to cloud
    cover these are your only choices.
    I have a way to calculate the variances that would make the ellipse of
    equal probability circular and so I was thinking in principle one
    could take more sights of some of the celestial bodies than the
    others, averaging so reducing the variance.
    How realistic a scenario is this and is there some literature on the idea?
