New graphs from AIMLESS against `batch' or image number. (a, c) Nominal resolution estimated as the point at which 〈I/σ(I)〉 falls below 1.0, showing a trend to lower resolution with increasing radiation damage, with both values for individual batches and values smoothed over a 5° range. (b, d) Cumulative completeness for all data and anomalous differences. (a) and (b) show that in this good case the damaged data in the last third of the sweep can be safely discarded without reducing the completeness. (c) and (d) show graphs for a poor and incomplete data set from two crystals. At the end of this data collection the anomalous data are still very incomplete. Breaks in the x axis separate the two crystals.
