Nanoscale Crystal Grain Characterization via Linear Polarization X-ray Ptychography: Raw data

File Description:

energy_rot1.dat, energy_rot2.dat

List of energies that were taken in the spectroscopy scans of two sample orientations. Unit is KeV.

P5_rot1_amp.tif, P5_rot2_amp.tif:

Tiff stacks of absorption images of the sample scanned across Vanadium K-edge at two perpendicular orientations relative to beam polarization. Pixel values are in range of [0,20000], which equal [Normalized transmission]*20000.

P5_rot1_phase.tif, P5_rot2_phase.tif:

Tiff stacks of phase images of the sample scanned across Vanadium K-edge at two perpendicular orientations relative to beam polarization. Pixel values equal [Real part of refractive index(Delta)]*[Factor]*10000, the factor is given in separate files.

delta_factor_rot1.dat, delta_factor_rot2.dat

List of factors to calculate delta values from phase images for each energy. The factor has no unit.
