[daip] Loading ATCA data {External}

[Andy Biggs]

Hi,

I'm trying something that I've never done before - to load ATCA data 
into AIPS. I'm falling at the first hurdle - ATLOD reports:

ERROR  3 ON UNIT TTDEV01         , GETTING HOST/SERVICE BY NAME
  ZMSGOP: ZTTOPN RETURNS ERROR =   1 FOR LUN =   6
ATLOD1: Dropping all flagged visibilities.
ATLOD1: Dropping autocorrelations.
ATLOD1: Vis weights set to integration time in units of 15 sec
ATLOD1: Averaging all pulsar bins
ATLOD1:
ATLOD1: Processing file:  1
ATLOD1: Input polarizations: XX,YY,XY,YX
ATLOD1: POLDEC: UNRECOGNIZED POLARIZATION TYPE.
ATLOD1: Purports to die of UNNATURAL causes
ATLOD1: localhost    31DEC23 TST: Cpu=       0.0  Real=       0
AIPS 1: Resumes

I'm running with APARM=-1,0 which appears to be the recommendation.

Looking in the FITS file, the Stokes values do look wrong in that 
CRVAL=5 whereas I would expect -5 for XX. Changing CRVAL3 to -5 and 
CDELT3 to -1 doesn't help.

I don't know what the first bit of the message 'ERROR  3 ON' means.

As this is my first time with ATCA, I might be doing something really 
stupid, but if you could help, that would be great. I'm trying to load 
an RPFITS file that I downloaded from the ATCA archive.

This is on 31DEC23.

Thanks,

Andy
