        Each subdirectory within this directory contains all the kernels of     
        the same type that have been generated for the Rosetta Mission.         
                                                                                
           ck:       Kernels that contain orientation for the spacecraft and    
                     some of its structures, (solar arrays, for instance).      
                                                                                
           ek:       Event kernels are not generated for Rosetta;               
                     therefore, this directory is empty.                        
                                                                                
           fk:       Kernels that define reference frames needed for the        
                     Mission.                                                   
                                                                                
           ik:       Kernels for the instruments on board the spacecraft.       
                                                                                
           lsk:      Leapseconds kernel.

           mk:       Meta-kernel files (a.k.a "furnsh" files) that provide 
                     lists of kernels suitable for a given mission period.                                        
                                                                                
           pck:      Kernels that define planetary constants.                   
                                                                                
           sclk:     Spacecraft clock coefficients kernels.                     
                                                                                
           spk:      Orbit kernels, for the spacecraft and other solar system   
                     bodies.                                                    
                                                                                
                                                                                
        Note that under each directory there is a subdirectory called           
        former_versions, that stores all kernels that have been superseded by   
        new kernels. You shouldn't use the kernels under these subdirectories.  
                                                                                
                                                                                
ROSETTA SPICE Kernel Naming Convention                                   
--------------------------------------------------------                                  
                                                                                
        Please refer to the aareadme.txt in each of the subdirectories for     
        information on the naming convention for the specific type of kernels.  
                                                                                
                                                                                
Usage of the SPICE Kernels for JUICE                                 
--------------------------------------------------------                           
                                                                                
        At least a basic knowledge of the SPICE system is needed in order to    
        use these kernels. The SPICE toolkit provides versions in Fortran       
        (SPICELIB), C (CSPICE), IDL (icy) and Matlab (mice), and the user can   
        choose any one that suits him/her.                                      
                                                                                
        The SPICELIB routine FURNSH, CSPICE function furnsh_c, and icy routine  
        cspice_furnsh load a kernel file into the kernel pool as shown below.   
                                                                                
           CALL FURNSH  ( 'kernel_name' )                                       
           furnsh_c     ( "kernel_name" );                                      
           cspice_furnsh, 'kernel_name'                                         
           cspice_funsh( 'kernel_name' );                                       
                                                                                
        In the case when two or more files contain data overlapping in time     
        for a given object, for binary kernels, the file loaded last takes      
        precedence.                                                             
                                                                                
        If two (or more) text kernels assign value(s) using the '=' operator    
        to identical keywords, the data value(s) associated with the last       
        loaded occurrence of the keyword are used -all earlier values have      
        been replaced with the last loaded value(s).                            
                                                                                
                                                                                
-------------------
