Extra data related to the Cassini SP-Kernels
============================================

   This directory contains value added elements related to SP-Kernels,
   which are currently limited to only one kind of information -- the
   formal SPK position uncertainty tables (covariance matrix tables)
   provided in the ``covtab'' subdirectory.


Formal SPK position uncertainty tables
======================================

   The subdirectory ``covtab'' contains table files providing the
   formal position uncertainties of Cassini's reconstructed ephemeris
   provided in the SPK files produced by the CASSINI NAV Team. For more
   information, see the file ``covtab/covinfo.txt''.
