\caption{Gravitomagnetic and classical nodal precession
coefficients, in \asec. The coefficients $\dot\Omega_{.\ell}$ are
$\partial\dot\Omega^{J_{\ell}}_{\rm class}/\partial J_{\ell}$ and
refer to the classical precessions induced by the oblateness of
the central mass. The numerical values of Table \ref{astropar}
have been used in Eqs.~(1) and (5) (see below).
$\dot\Omega_{\rm class}$ are the nominal centennial rates released
at {\tt http://ssd.jpl.nasa.gov/elem$\_$planets.html}. They
mainly include the $N$-body secular precessions. } \label{prec}
