Extraction of 1D intensity profiles from a 2D diffraction pattern. (a) Diffraction pattern from a textured aluminium sample (undulator gap 30 mm, exposure time 3.37 µs). (b) Diffraction intensity as a function of azimuthal angle φ, obtained by integrating over the q range 2.65–2.85 Å−1. (c) Diffraction intensity as a function of scattering angle 2θ, obtained by integrating over the φ range 165–185°. (d) Diffraction intensity as a function of first-harmonic scattering vector q, obtained by integrating over the entire φ range. |
