 \item \textbf{SKW}  Skewness of surface elevation sampled at zero slope. This is the $\lambda_1$ parameter defined in \cite{Barrick&Lipa1985} or $\lambda_{3,0,0}$ in \cite{Srokosz1986}. It is computed from the second order correction to the surface elevation, using ECWAM code by P. Janssen.
-\item \textbf{EMB} this is  $-\gamma/8 = -(\lambda_{1,2,0}+\lambda_{1,0,2}-2 \lambda{0,1,1} \lambda{1,1,1})/8 (1-\lambda_{0,1,1]^2)$, such that the mean sea level of points with zero slope

 is EMB$\times H_s$.
 \item \textbf{EMC} this is hte additional tracker bias coefficient equal to  $-\lambda_{3,0,0}/24$, which is specific to the choice of retracker, see the $J_z$ function in \cite{DeCarlo&Ardhuin2024}.
