Swidersk:
variegat: Warp corrected scans of the skull of a male Spermophilus variegates (UM 77495; Arizona, Cochise Co., 4 miles SW of Portal, collected by V. H. Calahane #315) . Scanned for Don Swiderski of the University of Michigan, Museum of Zoology. Scanned by Matthew Colbert on 7/28/00. Original scans on Archive 0253. Warp corrections applied by Holly Nance, April 2001.
Original scan parameters. II, 120 kV, 0.2 mA, no filter, air wedge, 160% offset, slice thickness 3 lines (= 0.1483 mm), S.O.D. 85 mm, 1200 views, 2 samples per view, interslice spacing 3 lines (=0.1483 mm), field of reconstruction 40 mm (maximum field of view 43.14 mm), reconstruction offset 530, reconstruction scale 33. Scanned in three-slice mode.
warpcorr (16bit): The above images modified with IDL software “Unwarp v.1.0” written by Dr. Richard Ketcham to correct for radial distortion of images introduced by ACTIS scanning software. Corrected images are now 522 pixels by 522 pixels, resulting in a revised field of reconstruction of 40.781 mm.
