      Description

      The current mechanism is to do a two fold process where smooth perturbations caused by the atmosphere and optics are represented as a single polynomial solution over the focalplane or chip. The higher frequency distortions caused by sensor effects are modeled in a different, unrelated way.

      Astrometry and all measurements need a way to represent these different distortions in a single self-consistent framework. This leads to the notion that the general concept of a "WCS" needs to be redefined to be more general.
