Category Description 

               Data items in the REFINE_LS_RESTR_NCS category record details
               about the restraints applied to atom positions in domains
               related by noncrystallographic symmetry during least-squares
               refinement, and also about the deviation of the restrained
               atomic parameters at the end of the refinement.  It is
               expected that these values will only be reported once for each
               set of restrained domains.
