There should be a message ahead of the TABINI message shown below. That is probably the most important one in the trail of messages. Error 1 from TABINI means bad inputs but there are several ways that can happen. A helpful diagnostic would be the output

<div dir="ltr">Dear Eric,
<div><br>
</div>
<div>I've got the correlated FITS file from our correlator and when I load it into AIPS I got the ERROR messages like:</div>
<div>CUSP > FITLD5: TABINI: ERROR ON TYPE AN DISK 1 CNO 2 VERSION 1<br>
CUSP > FITLD5: ANINI: ERROR 1 FROM TABINI OPCODE = WRIT<br>
CUSP > FITLD5: ANINI: ERROR 1 INITIALIZING ANTENNA TABLE FOR WRIT<br>
CUSP > FITLD5: AG2AN: ERROR 1 OPENING AN TABLE # 1<br>
CUSP > FITLD5: BT2AIP: ERROR 1 FORMING ANTENNA TABLE<br>
CUSP > FITLD5: ERROR 1 RETURNED FROM BT2AIP<br>
CUSP > FITLD5: Purports to die of UNNATURAL causes<br>
</div>
<div><br>
</div>
<div>I checked the loaded uv data that the AN and SU tables are missing. Is that a garbled file from the correlator, or is there any way to reconstruct those tables in AIPS? Thank you very much for your suggestion.</div>
