Figure 2
Plots from SCALA against `batch' (image) number (ac) for a good case with little radiation damage (see text) and (df) for a case with two crystals both suffering radiation damage. (ad) Mean scale [Mn(k)] and scale at θ = 0° (0k); these diverge if the relative B factor is large. (be) Relative B factor in the scaling; a large and declining negative value (e) indicates progressive radiation damage. (cf) Rmerge is roughly constant in the good case (c) but increases with radiation damage (f). (g) A plot of Rmerge against batch shows a single outlier arising from a weak or blank image: omitting this batch (h) removes this problem.
