Walt is correct, the denzo/HKL2000 is an exception. It integrates all
reflections that cross the Evald sphere, due to having special treatment
of reflections with large Lorentz correction. It works fine in normal
cases, even with somewhat misaligned rotation axis. These reflections
are measured more precisely, although maybe somewhat less accurately.

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

Dear CCP4BB users,
I have a question about Mosflm. The manual says green predictions have
"reflection width greater than 5 degrees" and will not be integrated.
I always
assumed it should have something to do with Lorentz factor but not
quite sure.
Why is it so? I'm not aware of such geometrical restriction in
HKL2000.
Thank you!
Walt
