Values of the coefficients J sub ij and J sub ij of the expansion into spherical harmonics of the surface of the Moon as this is presented by the Selenodetic Control System of the Aeronautical Chart and Information Center, ACIC, of the U. S. Air Force, are derived. Data for the Marginal Zone are taken from the maps of Watts and Hayn and the measurements of Davidson and Brooks. It is found that the present values are in good agreement with those derived on the basis of the same data derived by Schrutka-Rechtenstamm and the Army Map Service. The ACIC Control system approximates best the figure of the Moon as this is derived from the study of its physical libration on the assumption of homogeneity. Author
