 which will plot the 3-D shape of the apparent horizon surface.
 
+The \verb|src/misc| directory of the \thorn{AHFinderDirect} source
+code contains several perl scripts which are useful in visualizing
+\thorn{AHFinderDirect} output.  In particular, the script \verb|select.plane|
+selects a particular 2-D plane.  If you put this in your Unix path,
+it can be used with a gnuplot command like
+\begin{verbatim}
+splot '<select.plane xy <h.t105.h4.gp' using 4:5 with lines
+\end{verbatim}
+to show the shape of an apparent horizon in the xy plane.%%%
+\footnote{%%%
+	 Note that this script isn't very smart: it doesn't
+	 know about the \thorn{AHFinderDirect} local coordinate
+	 origin.  That is, for example, if you select the $xy$
+	 plane, you're selecting the \emph{global} $xy$ plane
+	 ($z=0$).
+	 }%%%
+
 Another Visualization option is OpenDX (\verb|http://www.opendx.org/|).
 Thomas Radke's has written some OpenDX macros
