Height of equivalent water columns taking the effect of the loading into account.
The coefficients of the kernel defined in \eqref{eq.kernel} are
\begin{equation}
k_n = 4\pi G \rho R\frac{1+k_n'}{2n+1},

where $G$ is the gravitational constant, $\rho$ is the \config{density} of water
and $k_n'$ are the load Love numbers.
