Measurement geometry and the number of pixels per q bin. Assignment of the pixels in two dimensions to q bins for different positions of the beam centre on a PILATUS 100K detector, with an X-ray energy of 17.4 keV and a sample–detector distance of 1.11 m. (a) Configuration with the beam centre aligned on the top left corner of the detector. (b) Setup with the beam centred on the detector. The insets show the resulting pixels per q bin N(q). Further beam centre positions are depicted in Fig. S4. |
