Frank, Sorry, but I don't understand what you are saying: >It's no longer >necessary to do this algorithmically. Just open a virtual almanac page. >Take a look at this message on the list from last summer where I talked >about the calculations: >http://www.i-DEADLINK-com/lists/navigation/0407/0005.html I read this message. In it you said: >This web tool is doing relatively little calculation. The positions of >the Sun, Moon, and planets are stored in a ten megabyte database to the >nearest arcsecond. These positions are originally from the JPL numerical >integrations, so >they are intrinsically very good. But where did you get this database from? And where can I get this database from? Except by programming Meeus's many pages formula. Alex.
