+   The acausal bond graph of system \textbf{RODa} is
+   displayed in Figure \Ref{RODa_abg} and its label
+   file is listed in Section \Ref{sec:RODa_lbl}.
+   The subsystems are listed in Section \Ref{sec:RODa_sub}.
+
+{\bf RODa} is essentially as described in Figure 10.2 of
+``Metamodelling''. It has an additional port ``[angle]'' to provide
+access to the rod angle.
