I am trying to work out a historical problem utilizing the Polaris-table data from 1998.
I understand that if I have a Nautical Almanac for a given year, that the sun's GHA/Dec numbers will be reusable four years later. That is, if I have an almanac for year 2011, the sun's data should work pretty well for year 2015.
Question #1: Is this also true of the Polaris tables?
Question #2: If the answer to question #1 is "no" then does anybody have a scan of the Polaris tables that they can post from 1998 specifically?
Question #3: If the answer to question #1 is "yes" then does anybody have a scan of the Polaris tables that they can post from any one of the years 1994/1998/2002/2006/2010/2014?
Thanks,
Bob Goethe
