      <Description>
        * CSO The body-Centered Solar Orbital frames for the Rosetta primary target comet 
        67P/Churyumov-Gerasimenko, incidental target comet 45P/Honda-Mrkos-Pajdusakowa   
        (Rosetta passed through its ion tail in July 2006), and  
        secondary targets asteroids 2867/STEINS and 21/LUTETIA are named  
        '67P/C-G_CSO', '45P/H-M-P_CSO', '2867/STEINS_CSO', and '21/LUTETIA_CSO'.  
        These frames are defined as a two-vector style dynamic frames as follows:
 
      -  The position of the sun relative to the body is the primary
         vector: the X axis points from the body to the sun.

      -  The inertially referenced velocity of the sun relative to the
         body is the secondary vector: the Y axis is the component of
         this velocity vector orthogonal to the X axis.

      -  The Z axis is X cross Y, completing the right-handed reference
         frame.

      -  All vectors are geometric: no aberration corrections are used.
 
    

  * CSEQ  The body-Centered Solar EQuatorial frames for the Rosetta 
   primary target comet 67P/Churyumov-Gerasimenko and secondary target 
   asteroid 21/LUTETIA are named '67P/C-G_CSEQ' and '21/LUTETIA_CSEQ'. 
   These frames are defined as a two-vector style dynamic frames as 
   follows:
 
      -  +X axis is the position of the Sun relative to the body; it's
         the primary vector and points from the body to the Sun;

      -  +Z axis is the component of the Sun's north pole of date
         orthogonal to the +X axis;

      -  +Y axis completes the right-handed reference frame;

      -  the origin of this frame is the body's center of mass.

   All the vectors are geometric: no aberration corrections are used.

   * C_G-CK  C_G comet fixed frame (CK frame) 
 
     A body-fixed frame is defined using standard
     body-fixed, CK-based frame formation rules:
   
      -  +Z axis is toward the North pole;

      -  +X axis is toward the prime meridian;

      -  +Y axis completes the right hand frame;

      -  the origin of this frame is at the center of the body.

   The orientation of this frame is computed by evaluating 
   corresponding C_G comet attitudes kernels.</Description>
