  The Crab Nebula has long been the standard reference point source for
very-high-energy (VHE, E $>$100 GeV) gamma-ray observatories such as VERITAS.
It has enabled testing and improvement of analysis methods, validation of
techniques, and has served as a calibration source. No comparable extended
source is known with a high, constant flux and well understood morphology. In
order to artificially generate such a source, VERITAS has performed raster
scans across the Crab Nebula. By displacing the source within the field-of-view
in a known pattern, it is possible to generate an extended calibration source
for verification of extended source analysis techniques. The method as well as
early results of this novel technique are presented.
