When I open a AARTFAAC fits file or parse the AARTFAAC fits stream i'm missing:

bandwidth information. For LOFAR that is the RESTBW FITS heade
Integration time. LOFAR fits files container a END_UTC field which you can use in combination with the start time to determine the integration time

also astropy gives a warning when I open a AARTFAAC fits file:

astropy:FITSFixedWarning: The WCS transformation has more axes (2) than the image it is associated with (0)

Noted! This will be fixed in the new imager where we will create fits products directly from the data without going through casacore first.
