title: Raw data for "Multimodal imaging of cubic Cu2O@Au nanocage formation via galvanic replacement using X-ray ptychography and nano diffraction"

description: <strong>Raw data for "Multimodal imaging of cubic Cu2O@Au nanocage formation via galvanic replacement using X-ray ptychography and nano diffraction"</strong> The file "raw_data_ptychography_waxs.zip" contains one HDF5 archive for each scan. The archives are structured as follows: section experiment: identifiers of the lightsource, beamline, beamtime, session number, and scan number section measured: N diffraction patterns of size 512x512 px used for ptychography N WAXS patterns of size 514x1030 px N scan positions in mm one detector mask of size 512x512 px used for ptychography one detector mask of size 514x1030 px used for WAXS slice separation in mm for multi slice reconstruction section parameters: distance between sample and forward detector (ptychography) in mm pixel size of forward detector (ptychography) in mm photon energy in keV cropping of diffraction patterns in px used for ptychographic reconstruction The following lists show the scan numbers with their corresponding reaction times and slice separations for the in situ series recorded during growth of Cu<sub>2</sub>O nanocubes, as well as galvanic replacement with Au measured out of focus and in focus.
