Dear Walt,
As Tim has said, this is indeed related to the Lorentz
correction. These reflections have a large Lorentz correction which is also
very sensitive to the crystal orientation, so any small error in orientation
can result in a big change to the Lorentz correction and thus to the corrected
intensity. However, the default maximum reflection width can be changed
(Experiment settings, Advanced Integration) and sometimes this is necessary to
avoid excluding too many reflections in cases where the mosaic spread is very
high (> 1° say) or the mosaic block size is small.
I think this feature is common to all integration programs, although the
default settings may well be different.
Best wishes,
Andrew
