    All correct given that the sights are spread around more than 180 deg
    of azimuth. But what happens when the sights are all taken from, say,
    the western half of the sky? Now, our poor navigator will be in the
    hat only 2/9 of the time. This is why you want a good spread of azimuths
    in your sights. If there are systemic errors, then with a good spread
    there is a good chance they will somewhat "cancel" and the center of
    the derived hat will, on the average, be closer to your real position.
