Dear Fred and Phil,

However there is no refinement of these parameters in XSCALE so if you need
to scale together several crystals (e.g. very small crystals that show
severe radiation damage after a few degrees) you end up with a  sub-optimal
combined dataset after XSCALE. I thought SCALA can take care of that and
define cell parameters that fit best all data as scalepack does when it
considers all separate frames , from all crystals where-as the input to
XSCALE is not separate frames but complete datasets).

Peter.
