Approximation of the Geometric Figure of the Moon Using Spherical Harmonics (Approksimatsiya Geometricheskoi Figury Luny s Pomoswchyu Sfericheskikh Funktsii),

Abstract

To represent the figure of the moon by means of spherical harmonics, the lunar surface was divided into 398 equal areas. Absolute heights of the visible lunar surface were picked up from the gyposometrical chart of the moon prepared by the Kiev Observatory. Absolute heights of the far side and the marginal zone of the moon were estimated using the relations between heights of the lunar and equipotential surfaces derived from data of the lunar artificial satellites 'Luna 10' and 'Orbiters 1-4'. Values of the 36 harmonic coefficients are calculated in five variants.
