course this does take a bit of time which isn’t always available.
Good luck

Dear all,
The attached diffraction image has a shadow
Dear Abishek,
shadows should be excluded from processing since the outlier rejection
algorithms cannot distinguish between weak and shadowed reflections!
In XDS, you could use a generous static mask (UNTRUSTED_*), or a dynamic mask
as specified by FILTER.HKL.
HTH,

Dear all,
The attached diffraction image has a shadow at the right edge. It moves from
the top to the bottom right corner. I was wondering if anyone knows what it
could be and whether it would affect data processing?
Thank you
Abhishek
This looks like the cryo-stream is too close to your crystal. I have seen this
before on our home source.
