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

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 Cu2O nanocubes, as well as galvanic replacement with Au measured out of focus and in focus.
