    Re: Possible limitaion for lunar distance measurement
    From: Wolfgang K�berer
    Date: 2009 Feb 28, 19:02 +0100

    Dear all,
    I think Frank's response to Kent's post may be misleading:
    
    The passage quoted by Kent's colleague is taken out of: "Lehrbuch der
    Navigation. Herausgegeben vom Reichs-Marine-Amt. Zweite umgearbeitete
    Auflage. Zweiter Band. Berlin 1906". And the passage says (in English):
    
    "Regarding the application of these different formulae for deducing the true
    distance the following holds true: Dunthorne's formula (18), or formula 20
    deduced from it, can only be applied, if the distance is between 70d and
    110d. Formulae 21 and 23, on the other hand, can be recommended in all cases
    and are the only ones to be used beyond these limitations."
    
    That - to me - seem to be "reasons mathematical" not "practical". But I
    leave this to the mathematical minds of this group, as I am more of a
    historical bent, as you will remember.
    
    Wolfgang
