\caption{Parameters used in DE405 (and INPOP05) (Col. 2), and in INPOP06  (Col. 3),  to compute the tidal effects (see Sects.~\ref{Earth_deformation} and \ref{Moon_deformations}) and the Earth orientation. $\tau_{E21}$ and $\tau_{E22}$ are respectively the Earth's time delays for harmonics (2, 1) and (2, 2), and $\tau_{\rm M}$ is the time delays for the Moon. They are expressed in days and rounded to $10^{-10}$. C, M and R are respectively the maximum moment of inertia, the mass and the mean equatorial radius of the Earth.}
