tines that convert SPICE planes to data that
   define a plane are:

      <a href="cspice_pl2nvc.html">cspice_pl2nvc</a> ( Plane to normal vector and constant )
      <b>cspice_pl2nvp</b> ( Plane to normal vector and point    )
      <a href="cspice_pl2psv.html">cspice_pl2psv</a> ( Plane to point and spanning vectors )

   Any of these last three routines may be used to convert this
   routine's output, 'plane', to another representation of a
   geometric plane.
