Hi Gihan,
If you mean "sigma cutoff at 1" for reflection rejection criterion, don't
do it!
It is very biasing.
See
https://www.hkl.hkl-xray.com/alphabetical-scalepack-keyword-documentation#SIGMA%20CUTOFF
for nice explanation why it is bad.
This option is also present in process_hkl of CrystFEL. Don't use it.
The documentations warn it.
