Now I have the information needed to generate a proper patch. Looking at both patch files, I can see the approaches are slightly different. The first one (1-25-19) adds the check right after creating the `xy` array and returns a list of empty arrays. The second one (1-24-17) adds the check after the denormalize_sky call and returns `xy` directly.

The first approach is cleaner because:
|
|
1. It checks earlier (right after creating `xy`)
|
|
2. It properly returns a list of empty arrays matching the expected output format (one array per WCS axis)
|
|
|
|
Let me produce the clean patch in unified diff format:
