    For what it's worth, the lunar distances in the 1804 Nautical Almanac are
    wrong by up to one minute of arc by my calculations. So if you're trying to
    figure out where he "really was" based on the observations or if you're trying to
    determine how good his observations were, you may want to get modern ephemeris
    data, too.
