Meta-kernels for the Rosetta mission
====================================

   This directory contains the meta-kernel (MK) files (a.k.a "furnsh"
   files) that provide lists of the archived kernels included in this
   data set suitable for loading into a SPICE-based application via the
   high level SPICE data loader routine FURNSH. Using these MKs makes
   it easy to load, with one call, a comprehensive SPICE data collection
   for a given period. Like the text kernels archived in this data set,
   these MKs are UNIX text files that have lines terminated with a line
   feed character, LF (ASCII 10).

   The names of the MKs provided in this directory follow this pattern:

      ROS_Vvv.TM

   where ``vv'' is the file version.

   Multiple versions of an MK for the data set may exist if new kernels
   were added to the archive in a later release and the MK had to be
   updated to incorporate them. The reasons for adding new kernels
   include (but are not limited to) adding new kinds of kernels, adding
   new versions of existing kernels containing more complete or more
   accurate data, and adding new versions of existing kernels
   superseding any existing kernels that had errors. If more than one
   MK is present, then the file with the latest version number
   supersedes all earlier versions.

   Although the MKs were created such that on a UNIX workstation they
   can be loaded into a SPICE-based application directly from the root
   directory of the data set -- because the PATH_VALUES keyword is set
   to './DATA' and '/' is used as the path delimiter -- it is
   recommended that users make local copies of these files and update
   the PATH_VALUES keyword in each of them to point to the actual
   location of the data set's 'data' directory on their system.
   Additional changes including replacing '/' and '\' in all path
   specifications and converting UNIX line terminator to terminators
   native to the user's system may be required to use these MKs on
   non-UNIX workstation.

   The following guidelines were followed to pick and set priority --
   determined by the order in which the kernel files are listed, with
   the latest one taking precedence -- for the kernel files included in
   these MKs (in the file name patterns below "?" represents one
   character):

   The following kernels were intentionally not included in the
   standard meta-kernels:

      PCKs:

         -  67P/C-G orientation PCK because they have limited time
            applicability; instead the comet orientation should be computed
            using CKs containing data for the 67P/C-G_CK reference frame.

      DSKs:

         -  No DSK files were listed in MKs because SPICE Toolkits
            N0065 or earlier cannot load MKs with DSKs.

   However, there are now MK versions (ROS_WITH_DSK_V??.TM) that contain one
   DSK for each of the six targets (ROS_CG_M004_NSPCESA_N_V?.BDS,
   ROS_ST_K020_OSPCLAM_N_V?.BDS, ROS_LU_M003_OSPCLAM_N_V?.BDS,
   PHOBOS_M003_GAS_V??.BDS, DEIMOS_K005_THO_V??.BDS,
   TEMPEL1_9P_K032_THO_V??.BDS).
