Asteroid Itokawa P_constants (PcK) SPICE kernel file
===========================================================================

     By Hayabusa Joint Science Team, <unknown date>; miscellaneous comments
     added by Boris Semenov, NAIF/JPL, on September 24, 2009.


Summary
--------------------------------------------------------

     This PCK file contains Itokawa rotation constants, radii and 
     the definition of the Itokawa body-fixed frame, ITOKAWA_FIXED.

     The Itokawa rotation constants provided in this PCK are 
     from the data set catalog file for the Itokawa shape model 
     data set (HAY-A-AMICA-5-ITOKAWASHAPE-V1.0) by the Dr. Robert W. 
     Gaskell, PSI.


Rotation constants for asteroid Itokawa

     Itokawa rotation constants are provided in the keywords below.

     The Itokawa radii are provided in the keyword below.

ITOKAWA_FIXED Frame Definition
--------------------------------------------------------

     The ITOKAWA fixed frame is defined in the same as any other PCK
     frame:
 
        *  +Z along the North pole;
      
        *  +X toward the prime meridian;
      
        *  +Y 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 rotation constants provided in this PCK file.
