Figure 5
Options for pre-processing of diffraction data. Shown in (a) is a raw detector image recorded with an Eiger 4M detector. Modular gaps and hot pixels are represented by 216 counts. By defining a logical mask for hot pixels, modular gaps and the beamstop area (b), the masked pixels are set to zero in the diffraction pattern (c). (d) In addition, ROIs can be defined and data can be binned by binning factors along each dimension (here, binning factor 2 along each dimension). (e) Radial mask defining a range from 0.22 nm−1 to 0.38 nm−1 and (f) azimuthal mask ranging from 120 to 160°. |
