Problem with high-order .ahead and rotated fields
Description
Trying to scamp HSC images, I produced a .ahead including 2nd order terms (attached) to deal with the large field of view.
Then I scamped a number of HSC catalogs. Some were rotated by 90 deg.
The solution for the non-rotated images is great. But for the rotated images, the distortion maps show that the solution is completely wrong.
A small sample of files can be found on dance09 in:/raid/hbouy/hsc/small_list.txt

I placed the sample HSC files and their .ahead on morpho:/raid/hbouy/debug_scamp/902
