    I'd be interested in looking at your form Mike. It might even compel me to
    take another shot at this table. I first tackled them when I spent three
    months in a remote camp on the north Yukon coast in 1990. I had the midnight
    to 4AM watch and all I did was take star shots and reduce them with Admiral
    Davies' tables. After my penance was over, I concluded that: 1) the tables
    require too damn many steps and 2) a form would be helpful if one insists on
    using them.  I never followed up on the latter.
    
    As I said before: Admiral Davies was a very intelligent man but one has to
    consider that not all of us are so well endowed.
    
    cheers,
    
    Robert
