This directory contains M01 CKs providing nominal nadir-pointed
   orientation. Two of these files -- m01_sc_map_nadir.bc and 
   m01_sc_map_rec_nadir.bc -- are updated every time a new version of
   the merged ever-growing SPKs (m01_map.bc and m01_map_rec.bsp) is 
   delivered. The other files -- m01_sc_map*_rec_nadir.bc and 
   m01_sc_ext*_rec_nadir.bc -- provide orientation for earlier parts of 
   the mapping mission and correspond in coverage to the archived SPKs.

   Refer to the comments in the CKs for more details. Contact Boris
   Semenov (bsemenov@spice.jpl.nasa.gov) if you have any questions
   regarding this data.
