    There is a very nice web page written by J. Gottfred on the navigation 
    methods David Thompson used.
    
    See 
    
    http://www.northwestjournal.ca/dtnav.html#Art%20VII.%20Recomputing%20Thompsons%20Data�%20Greenwich%20Apparent%20Time%20by%20Lunar%20Distance.%20By%20J.%20Gottfred.
    
    Gottfred goes through an actual Thompson lunar distance observation in 
    detail, reconstructing the methods that Thompson used.
