In task #15637, the linear WCS solution has been found. But distortions still remain to be measured. So I am starting this new task for distortions.
The general parametric framework for WCS distortions are described in Calabretta et al.. The most common ones used in imaging are the TPV and SIP standards.
On a related note, I noticed this paper on arXiv today: Taheri et al. 2022. It describes a method of finding distortions, which may be of interest for us in this task. There are other papers/webpage/programs for this is well, we should keep a library of the related work here in this task.
