18493 reflections were collected using program Collect
("Collect" Data collection software, Nonius B.V., 1998)
The conditions were as follow : crystal to detector distance = 36. mm.
Scan angle = 1.1 deg 1 scans of 50 sec per frame.
Data collection was divided into 2 set(s)
with the following starting angles and number of frames :

Set 1 Theta = 8.80 Omega = 0.00 Kappa = 0.00 165 frames
Set 2 Theta = -8.50 Kappa = 109.00 Phi = 0.00 46 frames
Friedel pairs were averaged. Internal R = 0.04
