... of geopotential from analysis of laser measurements of Lageos-1 and Lageos-2 1988-2003 . ... From the analysis of laser ranging distances to the geodetical satellites Lageos-1 (1988-2003) and Lageos-2 (1992-2003), the estimate 0.0613 0.0013 is obtained for the dynamical Love number k d 2 (the scaling factor of the near-diurnal tidal variations induced by the fluid core in the coefficients c 2 1 , s 2 1 of geopotential). ...
