General information about SPICE FRAMES kernels                                
==============================================                                
                                                                              
   In the SPICE system, the FRAMES kernel (FK) contains information           
   required to define reference frames used in a particular mission. This     
   information includes sources of orientation and origin location for        
   these frames and inter-connections between these frames and other          
   frames supported within the SPICE system.                                  
                                                                              
   The frame definitions information contained in the FK files can be used    
   by a collection of subroutines that are part of the SPICELIB library,      
   the major component of the NAIF Toolkit. These subroutines can be          
   integrated into user application programs. Information about obtaining     
   the SPICE Toolkit is located in the "software" subdirectory of the         
   main directory of this dataset.                                            
                                                                              
   Refer to the Frames Required Reading (frames.req) document provided        
   with the toolkit or available from the NAIF Node of the PDS, to get        
   more information on how to access FK data.

   The New Horizons FKs provided on this volume are named according to        
   the following scheme:

      vNNN       is the file version number;                                  
                                                                              
   If multiple versions of an FK file are provided, always use the            
   latest version (unless an earlier version is needed for some special       
   reasons.)
