    Re: Rigorous v Approximate methods
    From: Kieran Kelly
    Date: 2003 May 15, 12:21 +1000

    I am attempting to write a paper on historical navigation methods using
    Lunar Distances and have come across numerous examples of sight reduction
    using a rigorous method as outlined in both Norie and Raper. However they do
    not say what is rigorous about the method and how it compares to the
    approximate methods also mentioned in both texts.
    
    I presume the texts are referring to solutions of the spherical triangles in
    the Lunar Distance reduction process but I am lost.
    
    Can someone direct me to material which explains the difference?
    
    Also I am trying to use graphical symbols in my paper sun as sun ll, moon ll
    but cannot find them in any program. Does anyone on the list have a set of
    symbols which I could use for incorporation in documents in a format
    compatible with a program such as photoshop.
    
    
    Regards
