Brief Summary
--------------------------------------------------------

     This directory contains the SPICE Spacecraft Clock-Kernel files for the
     JUICE spacecraft on-board clock.   


File naming conventions
--------------------------------------------------------

     The naming scheme for JUICE SCLKs is:
 
          juice_TYPE_YYMMDD_vNN.tsc

     where 

          TYPE     SCLK data type contained within the file:

                   fict:   ``fictional'' data;
                  
                   stre:   SCLK created using a 'stretch' strategy, i.e. TCPs
                           are considered only the time they start to be
                           applicable, and then the correlation is made by
                           linking these points, i.e. not taking into
                           consideration the gradient and offsets provided
                           within the TCPs;
                          
                   step:   SLKC created using a 'step' strategy, i.e.
                           additional TCPs are created between real ones in
                           order to match the time correlation provided by a
                           TCP packet N at 60 seconds before TCP packet N+1,
                           so that continuity is forced.

          YYMMDD   start time of applicability, i.e. either release date for
                   fictional SCLKs or date of the last TCP used to generate
                   the SCLK in stretch/step mode.

          NN       version number of the SCLK (with the same TCPs).
