Example far-field PXCT for the Toupy Tutorials

An experimental dataset obtained at the cSAXS beamline (PSI, CH) by applying PXCT to the characterization of a shaped fluid catalytic cracking (FCC) catalyst. The open-access publication is: da Silva, J. C., Mader, K., Holler, M., Haberthür, D., Diaz, A., Guizar-Sicairos, M., Cheng, W-.C., Shu, Y., Raabe, J., Menzel, A., van Bokhoven, J. A., “Assessment of the 3D pore structure and individual components of preshaped catalyst bodies by X-ray imaging”, ChemCatChem 7, 413-416 (2015) The file containing the data should be PXCTprojections.npz, which includes the complex-values PXCT projections. For the sake of speed and to reduce the computing resources required for this tutorial, the projections have been downsized (binned) by a factor 2, which also means the pixel size is twice larger than the original pixel size. Nevertheless, this does not affect the data processing step, which should be identical to the original dataset.
