   The intensity  data  were corrected for Lorentz and polarization effects
and   scale  variation   but an absorption  correction was
   judged not to be necessary in view of the  small observed
    variation in intensity
   of  a  360 \%  \y-scan  of a  close-to-axial reflection (-2,0,2).
The variance \s^2^(I)  was calculated  on  the  basis  of  counting
 statistics plus the term
   (PI)^2^,  where  P  (= 0.021) is the instability constant as
derived from the
   excess  variance  in the reference reflections (McCandlish, Stout & Andrews,
   1975).   Equivalent   reflections  were  averaged  and  stated  observed
if  satisfying the criterion I >= 2.5\s(I).
