Analytical Lunar Ephemeris: Delaunay's Theory

Abstract

Delaunay's constants have been substituted into our analytical solution of the main problem of lunar theory. The results are compared with Delaunay's reduced formulas. Corrections are proposed to four terms in the mean motion of the perigee, three in the mean motion of the node, 45 in the reduced expression for the latitude, and 49 in that for the longitude.
