Flip frequency axis in UV data?

Hey, does anyone know an equivalent of 'TRANS' in the UV domain? I have two datasets that I need to DBCON, but they are in reverse order (i.e. CDELT > 0 for one, and CDELT < 0 for the other). Is there a task to flip the UV sideband?

I have found the answer! The answer is the task 'FLOPM'.

You can find a task in Dave Green's homepage

Instructions are given how to install and use the task 'UVFLP',
to re-order channels within AIPS
