1				THIS STRUCTURE WAS BUILT USING DATA COLLECTED ON ONE CRYSTAL. THE CRYSTAL SUFFERED FROM MEROHEDRAL TWINNING, WHERE TWO TWIN COMPONENTS CONTRIBUTE TO DIFFERENT DEGREES TO THE DIFFRACTION INTENSITIES. THE DATA SET WAS MODIFIED TO REMOVE THE CONTRIBUTION FROM THE MINOR TWIN COMPONENT, BEFORE THE REFINEMENT. THE MODIFICATION IS CARRIED OUT BY REMOVAL OF SOME REFLECTIONS AND BY INTENSITY CORRECTIONS OF OTHERS. THE DEPOSITED STRUCTURE FACTORS HAVE BEEN MODIFIED.
