    Re: Sextant accuracy with short distance to horizon

    No, this could not have happened, as I use a calculator that has the
    nautical almanac programmed in.  All "reduction" is done in software, and I
    have been using this software for years and I have compared it to the
    printed almanac and it is in full agreement.  We took into account our
    height above the water, even measured the temperature and checked the
    pressure so as to have a more accurate correction for refraction.
    The calculator has a built-in clock and that clock was set to GPS time right
    before the sites were taken.  The date was certainly correct.

    Dear Dan,
    Concerning your repeaterd error of 68': might that be a systematic
    error in the reduction? E.g., you've opened the almanac on the wrong
    page... That's surely not meant as an insult. It happens to us all
    once in a while (or am I unique in this respect?)
