Bob,
I am having some problems with refining high energy X-ray data, and need
some help. What do I do with the IRAD term in the instrument parameter file
? I am not using a tube or anomalous scattering. Also for a analyzer set, i
guess IPOL has to be set to 1. Is that correct ?
many thanks,
Dimitri
