Back in the early 1980’s when using a
single counter diffractometer, we would collect the same 500 reflections at the
end of data collection that we collected at the beginning. The scale
factor between the two “batches” of reflections would be a direct measure of
the decay of intensity if the source intensity remained constant. This is essentially what Tim wrote. So just collect the exact same rotation
scan of images at the beginning and end of data collection. CrystalClear
will compute the scale factors for you and jdtplot will plot them for you. Jim From:
[EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of JXQI This is not a question
directly related to ccp4 as far as I can tell, but I'm hoping someone on this
list may have some insight. We are now trying a new
crystal mounting method, I want to know weather there is any decay of
intensities in the process of data collection.I use the R-AXIS IV++ imaging-plate
detector and the CrystalClear to process the data. If any
person has a reference, I would be grateful. Thank you in advance for
your help! Janxon |
