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 reviewers who complain about the Rmerge in the outer shell! Paired refinement is a good metric for determining if the new measurements add anything You could probably go a little further than you have, since the outer shell is also complete which suggests you have not hit detector limit… best wishes Graeme On 5 Jun 2018, at 10:29, Deepali Verma <[email protected]<mailto:[email protected]>> wrote: Dear all, I am trying to process a crystal data at 2.8Å and having CC1/2 is 0.771 (outer shell).
