Data Set Overview
      =================
      This data set contains radar-based shape models for small solar
      system bodies, generated by the method developed by Scott Hudson.
      (The Peter Thomas shape models, based on optical data, are included
      in a separate data set, EAR-A-5-DDR-SHAPE-MODELS-V2.0.)
 
      The current version of this data set contains shape models for the
      following asteroids:  216 Kleopatra, 1620 Geographos, 2063 Bacchus,
      4197 Toutatis (low and high resolution models), 4769 Castalia, 6489
      Golevka, 1998 KY26, ASTEROID 52760 (1998 ML14), and 25143 Itokawa.
 
      Parameters
      ==========
      The polyhedral shape models are specified by the coordinates of the
      vertices of the polyhedron in conjunction with the linkages of the
      vertices into triangular facets.  These files provide sufficient
      information for use in visualization applications such as POVray and
      DXF.  The origin of the models is the center of mass, and the axes
      are the principal axes.  For all the models except Toutatis, the z-
      axis is the spin vector or north pole.  For Toutatis, the z-axis is
      the long axis.  Toutatis is in a long-axis non-principal-axis
      rotation state.
