    Robin,

    I am not quite done reading your citations - but what great work so far!.
    Very well done!

    A note: I believe now I made a mistake in point 2 where I try to project one of the circles into a straight line. In order to be able to be projected into a straight line a circle on Riemann's sphere has to be a great circle, right?  But in general the Hc-circle around an GP is not a great circle. So, there is the error I made.

    Regards

    H
