DATA & FILE OVERVIEW
--------------------

This dataset contains:

cuttlefish_metal_diffuser.h5    This contains the data taken at ESRF ID19 beamline for the purpose of testing whether iron filings could be used as a diffuser for high energy speckle based imaging

DESY_gratings_refs.h5           and
DESY_gratings_sams.h5           These are the reference and sample frames for the data taken at the P05 beamline at PETRAIII to show that UMPA is compatible with data taken using 2D gratings

lmj_ddf_dataset.h5              This contains the data taken using the LMJ source to demonstrate DDF_UMPA at a laboratory source

versa_data.zip                  This contains the data taken at the Zeiss-Xradia Versa 510 at MuVis
