    Re: Mag. Variation

    I can't explain this to your satisfaction.You answered my questions that I
    posted.I did some research(Bowditch etc.)to try to understand how they did
    it.I understand what they were doing and  how the tables were used to arrive
    at the solution.
    I am not a mathimatician nor do I wish to delve deeply into theory of it.In
    all these examples I am more interested in the mechanics of each of these
    processes.I can go to Bowditch or some other publication and find the
    formuli or method to find what one needs to get a solution.
    So,in this sense I cannot explain to you or anyone your questions concerning
    the "restricted nav. triangle".
    I'm sure some one on list can explain it to your satisfation.Not what you
    wanted to hear but the best I can do.
    Happy to send some other examples of how ACG worked mag var in the bush, but
    you have to pay the piper first and explain it to me i.e. what was the basis
    of that technique, how it worked, what was he trying to achieve with the
    solution to that restricted celestial triangle?

    Keiran,I spent some time over the last few days studying and getting
    familiar with Gregory's technique you sent.It took some digging and
    refamiliarisation with the haversine tables but I see how and why it was
    accomplished.All my questions were answered.
    Do you have another technique for finding variation you can share with us?
