      Description

      Using lessons learned from DM-5701, create a more complex distortion model that cannot be represented from the basic models in GWCS or AST. A good example for this might be a rapidly varying sinusoidal tree-ring-like function that is not well represented by the standard polynomial basis functions. This will test our ability to extend each framework with new models that have not yet been decided on.

      Once completed, we could plug this back into the composite model in DM-5701.
