    Help Please - paper by Griffiths? on all haversine methods

    Happy Christmas, belated ...

    One of my presents was a computer failure coupled with a back up failure. Apple upgrade incompatability problem, suffered by more than a few of us.

    In trying to reconstruct my saved NavList references, there's one I can't find using  a normal for me search. Within a post whose Subject was, as I recall, not related to haversines, posted in the last year I believe, there was an enclosed  file I had saved. It's subject matter was derivations of all haversine solutions to all the classic sight reduction methods. I think the author of the paper was called Griffiths. Can anyone lead me to that post, please?

    All the best

    Michael Bradley
