don't you also need to consider higher order cubes? In radio astronomy
4D cubes, with polarization data, aren't that uncommon. Normally the
IQUV (or whichever) data are stored in different cubes, but imagine
if they are on the 'pixel' level. I could imagine theory data popping
up like that one day.
