University of Texas High-Resolution X-ray CT Facility Archive Rowe: Lycaenops_: Scans of the skull of Lycaenops angusticeps (UCMP 42701; Cistecephalus Zone, South Africa, Beaufort, Cape Province) for Timothy Rowe of The University of Texas at Austin. Specimen scanned by Matthew Colbert on 4 February 2016. 16bitTIFF: Scan parameters: NSI scanner. GE Large Spot source, 250 kV, 4.8 mA, 4 brass filters, Perkin Elmer detector, 0.5 pF gain, 1 fps, 1x1 binning, no flip, source to object 938.064 mm, source to detector 1486.43 mm, continuous CT scan, 2 frames averaged, 0 skip frames, 1830 projections, 7 gain calibrations, 15 mm calibration phantom, data range [-0.5, 8.5] (grayscales adjusted from NSI defaults), beam-hardening correction = 0.3. Post-reconstruction ring correction applied by Jessie Maisano using parameters oversample = 3, binwidth = 17, sectors = 60, center [569,469][569,473]. Voxel size = 138.4 μm. Total slices = 1900.
