One would expect that the spectral regions are treated as closed intervals in both cases. Consider another example where the upper bound is placed between the spectral axis values:
In the first case, 5499.0 Angstrom is included in the resulting spectral axis. In the second case, 5499.0 pix is excluded.
One possible solution would be to treat all spectral regions as closed intervals during region extraction.

The rules of including/excluding boundaries of a spectral region during region extraction might be confusing, consider this example:
One would expect that the spectral regions are treated as closed intervals in both cases. Consider another example where the upper bound is placed between the spectral axis values:
The resulting spectral axis is changed only in the "pixel" case. Final example:
In the first case,
5499.0 Angstrom
is included in the resulting spectral axis. In the second case,5499.0 pix
is excluded.One possible solution would be to treat all spectral regions as closed intervals during region extraction.
