Table 2. Anomalous signal calculation.

RPH: relative peak height is the ratio of the average peak height of peaks 1, 2 and 3 divided by the average peak height of peaks 7, 8 and 9 in the anomalous difference map calculated at 50.0–2.5 Å resolution. Map CC: map correlation coefficient between the S-SAD-phased map and the model-phased map at 50.0–2.5 Å resolution. Rcc: ratio of Map CC between the MDS data and the regular-exposed data of the same crystal.
