This is a 2D ptychography dataset recorded on the id01 beamline of the ESRF.

It can be analysed e.g. with the following quick script:

pynx-cxipty.py data=ResultsScan0013/data.cxi probe=focus,60e-6x200e-6,0.09 defocus=200e-6 algorithm=analysis,ML**100,DM**200,nbprobe=3,probe=1 liveplot saveplot

Or to also optimise the positions (as done in the output files):

pynx-cxipty.py data=ptycho-siemens-star-id01.cxi algorithm=analysis,ML**100,AP**200,positions=1,AP**50,DM**200,probe=1,nbprobe=3 probe=focus,60e-6x200e-6,0.09 defocus=200e-6 liveplot saveplot

The description of the CXI format can be found at http://www.cxidb.org.
To create a CXI file you can look at the code in pynx.ptycho.runner.runner.PtychoRunner.save_data_cxi()
