(a)–(c) Scattering from a local region of the sample in strain state S1. The gray scale shows experimentally observed intensities in a small sub-region of the detector in three successive ω intervals, with the black arcs indicating the azimuthal direction. The detector position is L1 = 6.372 mm downstream from the rotation axis. Simulated patterns are shown as colored contours in arbitrary units, ranging from blue as the minimum to red as the maximum. This 200×200 pixel region is <1% of the detector area. The axis labels correspond to pixel number.
