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

   This directory contains the SPICE Instrument Kernel files for the
   INTEGRAL remote sensing instruments.


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

   The naming scheme for INTEGRAL IKs is:

         integral_SC_INST_vNN.ti

   where

         SC       accronym of the spacecraft (required):

                     integral: for the INTEGRAL spacecraft;

         INST     instrument identifier (required):

                     ibis      for Imager Board the Integral Satellite

         NN       version number (required);

                  If multiple versions of an IK file are provided for an
                  instrument, always use the latest version (unless
                  earlier version is needed for some special reasons.)


Current IK Kernels Set
