Wed 12 Oct 2022 03:20:23 PM UTC, comment #3: Thanks Pedram. Just one thing: visualizing the distortion is not just useful for warping, it is generally useful in many different scenarios. That is why I recommended to add this option to the Fits program, not the Warp program (similar to how '--skycoverage' is an option to the Fits program).

Distortion (or even projection on large scales) causes different pixels to have different sizes on the World Coordinate System. With DS9, we can see the effect of the distortions on the coordinate system as lines, but we don't see the changes in area on a per-pixel case. However, this is important to understand when confronted with a new image with a new distortion (see bug #63171).
