REMARK   3  OTHER REFINEMENT REMARKS: DATA PROCESSING INDICATED THAT THE        
REMARK   3  CRYSTAL WAS TWINNED BUT THE EXACT NATURE OF THE TWINING WAS         
REMARK   3  NOT CLEAR. TREATMENT OF THE DATA WITH THE TWINNING UTILITY OF       
REMARK   3  CNS INDICATED UNEQUAL (MAJOR AND MINOR) TWINNING FRACTIONS,         
REMARK   3  BUT A REFINEMENT OF THE INITIAL MODEL, IGNORING THE TWINNING        
REMARK   3  AND CONSIDERING ONLY THE MAJOR TWINNING FRACTION, GAVE BETTER       
REMARK   3  STRUCTURAL RESULTS, WITH RELATIVELY REASONABLE FINAL R AND          
REMARK   3  RFREE.
