Example for statistical operations provided by the CNS language. `norm', `sigacv', `save' and `sum' are functions that are computed internally by the CNS program. Binwise operations are in italics (`sigacv', `save' and `sum'). The result for a particular bin is stored in all elements belonging to the bin. The $[\sigma_{A}]$ (`sigmaA') parameters are computed in binwise resolution shells. The $[\sigma_{\Delta}]$ (`sigmaD') and D parameters are then computed from $[\sigma_{A}]$ and binwise averages involving $[|{\bf F}_{o}|^{2}]$ and $[|{\bf F}_{c}|^{2}]$ . The binwise results are expanded to all reflections by the last three statements. `test' is an array that is 1 for all reflections in the test set and 0 otherwise. `sum' is a binwise operation on all reflections with the same partitioning used for the test set.
