Hi Ingo,

Scala might be beneficial after xds when several datasets need to be scaled
together. Scala will refine cell parameters to fit best all the datasets
together where as xscale uses as cell parameters those of the first dataset.
If you use xscale you have to be prudent in your choice of the first
dataset.

Peter.
