One of the antenna files contains the source of the problem I think.<br /><br />There are 10 antennas listed but the 9th and 10th rows list antennas<br />which have already appeared but assign them different, already used,<br />antenna numbers. This is fundamentally a problem and I am surprised<br />that 31DEC16 did not complain. Try concatenating but without any file<br />that has that sort of problem. That problem basically is telling AIPS<br />that there are 2 antennas numbered 5 (if I remember correctly) and<br />one numbered both 9 and 6.<br /><br />You could try using antname for its intended purpose. Set it up with <br />a sequence of all the antenna names you intend to use and then<br />run EVERY fitld with that set. This should fix things.<br /><br />i.e ANTNAME='AA','AP','AZ','JC','LM','PV','SM','SR'<br /><br />and more if there are any more<br /><br />Eric Greisen<br />
