That's correct, yes. If you've got proper FITS headers then everything
should go through fine. The only extra bits that would probably have to be
added to DATACUBE is putting in the observer's location on Earth (I do it in
ORAC-DR by creating an Astro::Telescope object from the FITS header, then
using that to give me the lat/long of the telescope). There are a few other
attributes that could be modified for greater accuracy, but I haven't
bothered with them at this point in time.
