Implementation Notes
========================================================================

   This file is used by the SPICE system as follows: programs that make
   use of this frame kernel must `load' the kernel, normally during
   program initialization. The SPICELIB routine FURNSH and CSPICE
   function furnsh_c load a kernel file into the kernel pool as shown
   below.

      CALL FURNSH ( 'frame_kernel_name' )
      furnsh_c    ( "frame_kernel_name" );

   This file was created and may be updated with a text editor or word
   processor.


Dawn Frames
========================================================================

   The following Dawn frames are defined in this kernel file:

           Name                  Relative to           Type       NAIF ID

   Dawn Target frames:
   -------------------
      CERES_FIXED             J2000                PCK            2000001


Dawn Target Frames
========================================================================

   This section of the file contains the body-fixed frame definition
   for one of the Dawn mission targets -- asteroids 1 Ceres.

   A body-fixed frame is defined for Ceres using standard body-fixed,
   PCK-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 rotation constants provided in the PCK file(s).
