This looks good to me!

what does DUCT mean? When I tried looking this up all I found was that this RPA has "a separate wide aperture sensor, a duct sensor"

I'm not sure if it's an acronym or just a name that's been capitalized (like MAG). I might need to drop this info since we don't include the duct files, which require an xarray load.

Removing these lines since duct is not yet supported
