The number "Unique reflections" given above refers to the "NON-ANOMALOUS" reflections (13861 reflections). However, separating the reflections on F(+) and F(-), the Phenix program gives a number of 26710 reflections for the refinement. The statistics (number of reflections) in resolution shells also refers to F(+) and F(-). Attention, these are very strong anisotropic data, so that the spherical completeness is relatively low.
