    Already did. Not only drawing but calculation.
    See my previous message where the formula is given.
    In the prism experiment you and Bruce are right.
    (And I am sorry for saying that you were wrong before
    I did the calculation).
    However it does not folloow that the prism experiment
    adequately describes the real situation.

    I think it does: if the anomalous refraction always decreases
    with height of the observer, than  the anomalous refraction from
    the space ship would be smaller than that from a sailboat.
    And we all agree that it is probably not smaller.
    In view of these thought experiments I suppose that
    anomalous refraction is not a monotone function of the height.
