  14248 reflections were collected using program Collect
 ("Collect" Data collection software, Nonius B.V., 1998)
 The conditions were as follow : crystal to detector distance =  39. mm.
 Scan angle =  2.0 deg 1 scans of  150 sec per frame.
 Data collection was divided into  1 sets
 with the following starting angles and number of frames :

 Set 1 Theta =    9.59 Omega =  180.00 Kappa =    0.00   64 frames
 Friedel pairs were not averaged. Internal R = 0.06

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value '4Fo^2^/(\s^2^(Fo^2^)+0.0004
Fo^4^)+1.0' was changed to 'calc'. New tag
'_refine_ls_weighting_details' was created. The value of the new tag
was set to 'w = 4Fo^2^/(\s^2^(Fo^2^)+0.0004 Fo^4^)+1.0'.
