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! Bill B
