Brief summary
--------------------------------------------------------
 
     This directory contains the SPICE I-Kernel files for the MRO
     spacecraft science instruments. All files are in IEEE text format and
     must be copied using ftp ASCII transfer to any non-UNIX workstation.
     The following files are present in this directory. (Only file names
     are shown; the file name extensions of the text IK files are always
     ".ti"):
 
           mro_crism_vNN    MRO Compact Reconnaissance Imaging Spectrometer
                            for Mars (CRISM) IK file containing instrument
                            mounting alignment and FOV geometry parameters;
 
           mro_ctx_vNN      MRO Context Camera (CTX) IK file containing
                            instrument mounting alignment and FOV geometry
                            parameters;
 
           mro_hirise_vNN   MRO High Resolution Imaging Science Experiment
                            (HiRISE) IK file containing instrument mounting
                            alignment and FOV geometry parameters;
 
           mro_marci_vNN    MRO Mars Color Imager (MARCI) IK file
                            containing instrument mounting alignment and
                            FOV geometry parameters;
 
           mro_mcs_vNN      MRO Mars Climate Sounder (MCS) IK file
                            containing instrument mounting alignment and
                            FOV geometry parameters;
 
           mro_onc_vNN      MRO Optical Navigation Camera (ONC) IK file
                            containing instrument mounting alignment and
                            FOV geometry parameters;
 
           mro_sharad_vNN   MRO Shallow Radar (SHARAD) IK file containing
                            instrument mounting alignment and FOV geometry
                            parameters;
 
     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.)
 
 
IK File Naming Schema.
--------------------------------------------------------
 
     The MRO IK files naming schema is as follows:
 
           mro_IIIII_vNN.ti
 
     where
 
           IIIII            is the instrument name (example: ``ctx'');
 
           NN               is the file version (example: ``01'' for
                            Version 0.1);
