Description
The new Wcs class should be able to apply transforms in a stack so that many different distortions as different scales can be corrected for separately (rather than trying to correct the whole mess with a single 2D polynomial). There is some work going on in the community around this. This task should include conversations with community leaders in this area.

Our whiteboard breakdown of the stories involved in this epic.
Slightly better picture of our whiteboard breakdown of the stories involved in this epic.
We need to make sure to motivate the requirement for C++ access to Wcs objects. Can we just send bare coordinate transform objects?
CameraGeom is an obvious place where this could be used. How are we dealing with that?
I note here that we overcommitted on this epic, but by doing so, 10-15 SP were spent in order to illuminate the fact that DM-3872 was no longer needed. Because the recommendation requires a rewrite, that work would have been wasted effort.
All stories completed, DMTN-010 published, RFC posted. We're done!
To kick things off, the Starlink AST library is relevant: http://starlink.ac.uk/ast.
