X-ray dataset for "Illumination improvements for high-resolution ptychography"

<p>We provide X-ray ptychography datasets used for publication &quot;Illumination improvements for high-resolution ptychography&quot;</p> <p>The provided datasets are stored in Matlab MAT files and they contain:<br> &nbsp; measured_intensities&nbsp;&nbsp;&nbsp; uint16&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; - photon counts measured by a 2D hybrid-pixel detector in every scanning position&nbsp; &nbsp;&nbsp;<br> &nbsp; probe_positions&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; double&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; - relative probe position already converted to units of the real-space pixel shift<br> &nbsp; detector_mask&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; logical&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; - mask which is true for good pixel and false for ignored (bad or missing) pixels<br> &nbsp; initial_probe&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; &nbsp;&nbsp; complex double - initial estimate of the reconstruction probe</p> <p>The pixel size for the FCC_particle datasets is 27.43nm and for the siemens_star datasets it is 9.97x14.16nm</p> <p>&nbsp;</p>
