    Re: Lunar mechanics and Double Alts.

    Dear Mr. Royer,
    Thank you for sharing your experiences with us.  It was certainly
    enlightening to read that your observed altitudes were within 0.1' of
    arc of your calculated altitudes.  It gives me something to aim for, as
    I still have standard errors of around 0.2' of arc, and the means only
    rarely get within 0.1' (although they are getting there more
    frequently!).  Part of it may be due to you superior sextant, but I am
    sure much of it is due to your superior technique, from years of
    experience.  I wonder whether sea officers just coming on board now
    will ever again achieve your level of expertise.
    Yours Sincerely,
    Fred Hebard
