CC1/2
Examples for citations from papers using (possibly among other criteria) CC1/2 and/or the paired refinement method (reference below) for finding the high-resolution cutoff.
- "In choosing our highest-resolution cutoff we chose shells, which still fulfil CC1/2 (ref. 57) >25% and I/σ(I) greater than or equal to 0.5 and which were supported by our results from the paired refinement method (ref. 57). Choosing a lower resolution cutoff did not improve the overall quality of the maps." Models were refined at 6.0 and 3.4 Å, respectively [1].

Data collection statistics are shown in Extended Data Table 1." That table shows high resolution values of 3.2 and 3.3 Å, respectively, with CC1/2 of 0.237 and 0.357, and I/σ(I) of 0.6. It also gives CC*, CCwork and CCfree and demonstrates that CCwork < CC*, as is to be expected.
