It's still there for spectropolarimetry, IRIS2, and MICHELLE. It should be
fairly easy to remove it, but I just haven't had the chance yet.

Yes, I am under the impression that some of these are bodges put into place to
get around Figaro's trouncing of the WCS. I think there are some simpler ways
to get the wavelength axis represented correctly with SpecFrames instead of
the old way with AXIS structures and all that. I just haven't had time to do
it because it's never been a priority for me.
