tested on a couple bias files atms_n20 and iasi_mtb and all is working fine

thanks @CoryMartin-NOAA testing again after merge of Kevin's PR

[BenjaminRuston]

this is working for me @CoryMartin-NOAA please merge if you're ready or let me know something you'd like me to test. I can't approve my PR

[CoryMartin-NOAA]

I'd like @ADCollard to give it a quick once-over but then I'm happy to merge it in.

The ctests all pass for me and I am happy with the changes. I checked the radiance and aircraft output files and the contents appear as expected.
