      | The number of files for each SPICE kernel type is shown in the table below for the missions specified. 
      An asterisk (*) indicates that one or more non-kernel files are also present; usually this is an 'aareadme'
      file that explains the kernel file naming convention. The count of the number of kernels is made ONLY
      in the primary directory; in some cases there are additional kernels in a subdirectory (for instance,
      older versions of kernels that have been replaced with newer versions).
