The Best Approximation to the Lunar Ephemeris: Comparison Between Cartesian and Spherical Coordinates
Abstract
A comparison between Cartesian and spherical coordinates is made for the uniform approximation to the lunar ephemeris. Best results apply for Cartesian coordinates where polynomials of degree 29 are valid for 31 days at the precision of The Astronomical Almanac ``Daily Polynomials''.
