The Clementine topography model is known as the Goddard Lunar Topography Model 2B (GLTM-2B). This is a 70th-degree and -order model, with extrapolation to the poles of the GLTM-2B data using GMT surface, the minimum curvature gridding program of Wessel and Smith (EOS, Transactions American Geophysical Union, v. 72, p. 441-446, 1991). The coefficients are in meters, and are referred to a spherical datum of radius 1738000 m. Thus, the degree zero coefficient is the actual mean radius, minus 1738000."

Each row in the table contains the degree index m, the order index n, and the coefficients Cmn and Smn.
