THE SELENODETIC CONTROL SYSTEM OF THE ARMY MAP SERVICE,

Abstract

Values of the coefficients of the expansion into surface harmonics of the lunar surface as presented by the Selenodetic Control System of the Army Map Service are derived. Data for the Marginal Zone are taken from the maps of Watts and Hayn and the measurements of Davidson and Brooks, and the far lunar side is assumed to be symmetrical to the near one. It is found that the present results agree with those derived from the data of Schrutka-Rechtenstamm and are close to the figures for a homogeneous Moon as far as the second zonal and sectorial terms are concerned. There is less agreement in the third surface harmonic and even less in the fourth. The results have little resemblance to those derived from Baldwin's data on exactly the same assumptions. It appears that at present the Selenodetic Control System of the Army Map Service should be rated as the best existing source, followed by the data of SchrutkaRechtenstamm. (Author)
