Figure 1.
Power spectra of the Primary Mission GRAIL gravity solution, GRGM660PRIM [Lemoine et al., 2013], GRGM900C, the new solution including Extended Mission data, and the unconstrained version of GRGM900C, where no Kaula constraint was applied. The power spectra of the coefficient standard deviations for GRGM660PRIM and GRGM900C are also shown.
