Hi Clemens,
Can you elaborate on the effects of improper inclusion of low
resolution (bogus?) reflections? Other than rejecting spots from
obvious artifacts, it bothers me to discard data. But I can also see
how a few inaccurate, very high intensity spots can throw off scaling.

Subject: Re: unstable refinement
* resolution limits: are you suddenly including all those poorly
measured or non existent reflections at the low resolution end (10A
and lower) that are only present because the beamstop masking wasn't
don properly during data processing/integration?
These bogus reflections can mess up your bulk-solvent correction and
scaling with weird effects. Better check the scale factors you're
getting during refinement and if they make sense.
Cheers
Clemens
