Dear Deepali, the best way to define the resolution cut-off is to check whether the data still contribute to model quality. You can easily check that by the procedure called "paired refinement" as described by Diederichs and Karplus (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3457925/

Usual recommendations are to have CC-half > 0.3 or 0.5 (these are usually not so far separated) For the most part the refinement software is smart enough to down-weight “noise” in the outer shell so there is very little penalty in including weak measurements, and you should put up a fight with

Dear all, I am trying to process a crystal data at *2.8Å* and having CC1/2 is 0.771 (outer shell). I just want to know the acceptable range of CC1/2. These are the statistics of the process data. Overall InnerShell OuterShell Low resolution limit
