Compensating like this is of course not the best (go and recollect!)
but still way better than unusable data in the meantime. In the case
Sergei originally described it would at least indicate what the
problem may be. Sergei did not say which detector was used for the
data collection so we don't know if it was a Pilatus or a CCD. Maybe
Sergei can fill us in on the details?



>The data that Sergei described were collected by yours truly at
beamline ID14-2 of the ESRF, so detector is a Quantum CCD. I collected
data for another protein crystal a few hours before with 0.5 degree
oscillations - no abnormal statistics here, so I don't suspect cryo or
loop instabilities are the underlying cause as suggested before.
The choice of 0.1 degree oscillations appears somewhat unfortunate in
retrospect, but this is what several programs (Best/mosflm/DNA)
suggested to reduce overlaps. The data were collected for the only
crystal that showed decent diffraction to ~3A out of more than 30-40
screened.
