Report of the Secretary of the Navy "We recognize in navigation two classes of astronomical problems; one possessing perfect accuracy of computation; the other uncertain, and approximate only in its results. The first class is, of course, always employed when the weather and other circumstances are favorable. The second class of problems, that which gives only approximate deductions, is never resorted to except from necessity. The latter, however, serves a useful purpose by enabling the navigator to know his position more nearly than he could otherwise do, and by often affording perfect security by informing him of the limit of safety, beyond which he should not venture." -------------------------- I would like to assign the latitude and longitude by the noon sun fix to the second class of problems. It can provide us with a useful figure of merit, albeit without perfect accuracy. Certainly, with a least squares curve fit, the method affords us a very reasonable fix. So if Frank wants to "trot out his hobby horse" one more time, I for one will applaud it. Proven?? A resounding YES!
