I don't know, but the explanation section of the N.A. says moon errors from the daily pages up to 0!3 are possible, augmentation error to 0!3 if not accounted for, and oblateness up to 0!2. The moon IS cel nav's wild child, which to paraphrase Peter scoots about in distance and declination like a ferret on speed. I certain I will soon learn the above is seldom significant to someone trying to work to 0!1 or 0!2.Bill --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to NavList@fer3.com To unsubscribe, send email to NavList-unsubscribe@fer3.com -~----------~----~----~----~------~----~------~--~---
