X-Ray Diffraction data from Protein tyrosine phosphatase 1B, source of 7MM1 structure

This data was collected with the Pilatus detector raised by two panels. This altered the beam center from that reported in the image headers and introduced a shadow on the detector. For data reduction, the beam center should be set to (290.5, 225.2), and the pixel mask provided in the "Processing Bundle" should be used. The experiment was conducted at 6.5 keV to improve the anomalous signal, but this introduced an additional harmonic in the incident X-ray beam. The resulting secondary diffraction pattern is only observed at low resolution, and was excluded from DIALS spot finding, indexing, and geometry refinement by setting d_max to 6 angstroms. The data was collected in two passes on the same crystal. Both passes were processed separately in DIALS and merged together in AIMLESS to yield the final merged intensities.
