      Description

      Once we have a composite distortion model from DM-5701, evaluate the performance of AST and GWCS over a range of numbers of pixels, likely from ~100 through full-CCD (4k^2).

      As part of this process, we will try to determine whether there is a way to efficiently warp images/postage stamps using python-only models in GWCS and whether bottlenecks could be worked around via optimizations in cython.
