The global lunar gravity field was determined from a weighted least squares analysis of the averaged classical element of the five Lunar Orbiters.The observed-minus-computed residuals have been reduced by a factor of 10 from a previously derived gravity field.The values of the second-degree zonal and sectorial harmonics are compatible with those derived from libration data.
