021_ALERT_1_A Ratio Unique / Expected Reflections too High ... 5.26 The expected number of reflections corresponds to that in the asymmmetric unit of the Laue group. Expected ratio: less-or-equal 1 for centro symmetric structures and less than 2 for non-centrosymmetric structures. Reasons to exceed those numbers can be: 1 - Systematic extinctions not omitted from the obsd data count. 2 - Refinement with redundant (i.e. not merged/unique) data set. 请问，这个A级错误该怎么解决呢？ 谢谢！ |
