    A question from the "no-nothing" cheap seats :-)
    Your online almanac lists the Sun's SD as 16!27, yielding a diameter of
    32!54. Does your SD calculation make any attempt at compensating for the
    irradiation fuzzy variable? If so, how?
    An aside to Greg: 0!06 from a highly-respected almanac with a small
    sextant sample--nice shooting!
