Full description
University of Texas High-Resolution X-ray CT Facility Archive Chin: SMIG-DMNH: Scan of a coprolite with partial crocodilian skull (SMIG-DMNH; DMNH uncat.; Hell Creek Fm., Montana, Late Cretaceous, Maastrichtian) for Karen Chin of the University of Colorado at Boulder. Specimen scanned by Matthew Colbert on 28 March 2018. 16bitTIFF: Scan parameters: NSI scanner. Fein Focus High Power source, 220 kV, 0.221 mA, brass filter, Perkin Elmer detector, 0.25 pF gain, 1 fps, 1x1 binning, no flip, source to object 300.0 mm, source to detector 1180.0 mm, non-continuous CT scan, 3 frames averaged, 0 skip frames, 3000 projections, 6 gain calibrations, 5 mm calibration phantom, data range [-10.0, 73.0] (grayscale adjusted from NSI defaults), beam-hardening correction = 0.175. Post-reconstruction ring correction applied by Jessie Maisano using parameters oversample = 2, radial bin width = 31, sectors = 96, minimum arc length = 1, angular bin width = 9, angular screening factor = 1. Voxel size = 56.1 μm. Total slices = 1969.
