Structural refinements on (a) 250 Hz reciprocal-space (PXRD) data (Rwp = 2.8%) and (b) 250 Hz real-space (PDF) data (Rp = 56.1%) after ∼5.3 s. (c) Average crystallite sizes obtained from Rietveld refinements on 250 Hz PXRD data (top, blue dots) and average coherently scattering domain sizes obtained from real-space refinements on 250 Hz PDF data (bottom, green dots). Refinements were performed on 1 Hz reciprocal-space and PDF data as well. Refined average crystallite sizes and average coherently scattering domain sizes from these refinements are overlaid on the respective curves with black dots. (d) Normalized standard deviations on refined parameters from refinements on 1–250 Hz PDFs in the time interval 20–25 s. The refined values are normalized to the mean within the time interval by xnorm = [(x - {\overline x}) / {\overline x}] and the normalized standard deviation is subsequently calculated as σnorm = [[({1 / N}) \sum \nolimits_{i=1}^N (x_{{\rm norm},i} - {\overline x}_{\rm norm})^2 ]^{1/2}].
