In reference to the almanac page posted by Walden that shows the lunar distance for Antares on 8/1/773 at noon to be 48-18-36. I have some questions. 1) What delta T would be appropriate for that date? 2) Would that distance be based on topo position or apparent position or something else? And what location would be assummed? 3) What distance is given by current almanac programs for that date? Just curious and trying to reconcile my almanac program with this data. My program gives a lunar distance using dT =15 of topo (greenwich) 48-12-37 apparent 48-14-56 --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "NavList" group.
