Book excerpt: These tables for A.D. 2 to A.D. 1649 are an extension, with some improvements, of earlier ones for 601 B.C. to A.D. 1. As before, they give the geocentric positions (tropic celestial longitudes & latitudes, i.e. with respect to the mean equinox of date), in units of 0 degrees.01 for the Sun & planets, & 0 degrees.1 for the Moon, at 16h Universal Time - 4 P.M. Greenwich Civil Time - 7 P.M. local mean time of 45 degrees East longitude (Babylon), on the indicated dates, all in the Julian calendar, hence for Julian dates 5n + 1/6 for the Moon, Mercury, & Venus, & 1-n + 1/6 for the Sun, Mars, Jupiter, & Saturn. The same adaptation of the theories of Leverrier, Gaillot, & Hansen, with modified elements by Schoch, was used as before, except as noted below. The chief change has been to improve the positions of Jupiter & Saturn. Tables.
