The GEOMETRY directory contains a meta-kernel with the recommended set
of SPICE kernels to use with the shape model data in the DATA directory.

The SPICE kernels thare are recommended for use in the meta-kernel are:

dawn_v14.tf (or later)                 : Ceres Surface name/ID mappings
dawn_ceres_grv171219_v1.tpc            : Ceres rotation parameters
de432.bsp                              : Planetary ephemeris
sb_ceres_grv_171219.bsp                : Ceres ephemeris wrt Sun
dawn_grv_150204_150424_171219_v1.bsp   : Dawn ephemeris wrt Ceres
dawn_grv_150424_150701_171219_v1.bsp   : Dawn ephemeris wrt Ceres
dawn_grv_150813_151023_171219_v1.bsp   : Dawn ephemeris wrt Ceres
dawn_grv_151213_160902_171219_v1.bsp   : Dawn ephemeris wrt Ceres

Files ending with "*.bc" are Binary C-Kernels (CK), containing orientation
parameters. Fils ending with "*.bsp" are binary Spacecraft and Planetary
Files (SPK), containing information on spacecraft and planetary epheremis.
Files ending with "*.tf" or "*.tpc" are Frame kernels (FK), containing
name/ID mapping configuration and frame definitions for SPICE.
