Data were collected on a Rigaku Rapid which has a quarter 
chi circle and a 200 degree curved image plate at a fixed 
distance of 127.4mm.  Strategy was optimized using the 
CrystalClear software.  The completeness is the best 
that can be obtained with this geometry. The missing data are not cusp 
data but mostly high angle data.
Also the use of HKL2000/SCALEPACK lowers the number 
of observed data as inconsistent equivalents are removed 
from the data set and not included in the collected total
