   The acausal bond graph of system \textbf{ROT2} is
   displayed in Figure \Ref{ROT2_abg} and its label
   file is listed in Section \Ref{sec:ROT2_lbl}.
   The subsystems are listed in Section \Ref{sec:ROT2_sub}.

\textbf{ROT2} implements a 2D rotational {\em transformation\/} in
terms of a set of {\em transformers}. A flow expressed in the $XY$
coordinates of Figure \Ref{ROT2_abg} is transformed by \textbf{ROT2}
into the coordinates of $xy$. The corresponding (energy conserving)
effort transformation is implied by \textbf{ROT2}.

%SUMMARY ROT2: 2D rotational transformer
%DESCRIPTION {ROT2} implements a 2D rotational transformation in terms
%DESCRIPTION of a set of transformers. A flow expressed in the X-Y
%DESCRIPTION coordinates is transformed by ROT2 into the coordinates
%DESCRIPTION of x-y. The corresponding (energy conserving) effort
%DESCRIPTION transformation is implied.
%DESCRIPTION Ports X and Y correspond to the old coordinate system
%DESCRIPTION Ports x and y correspond to the new coordinate system
%DESCRIPTION Port theta is the angle of XY with respect to xy.
