In MWAX, any observation can be interrupted by a trigger which will cause some or all of the /dev/shm buffer of .free files to be dumped and archived as .sub files.
This means there could be an observation which has MODE=MWAX_CORRELATOR and has some number of visibility files AND subfiles. There should be no trouble with using mwalib to read the correlator files/metafits, however there may be issues using a metafits which specifically says "MWAX_CORRELATOR" for reading the voltage .sub files. Need to test this scenario and cater for it.
