		A \textbf{summary of dependencies} between $\dLv$-related quantities derived in \S\ref{sec:diff_rte}.
		An arrow from A to B indicates that A depends on B. 
		%The cycles in this diagram indicate that the whole system effectively forms a transport equation of $\dLv$, as previously showed by the DRTE~\eqref{eqn:rte3d_drte}.
