PA: fringes only in subband 1 (problem configuring for wideband).
CD: RTFC reported no fringes. However, we see weak fringes in the pipeline. (Possible pointing problem?).
HO: Effectively RCP only (weak LCP fringes seen on strong sources).
AT: The ATCA observation was out of synch with other antennas due to a CABB schedule error (too many scans in original vex which was then incorrectly modified). Note that this means CABB was often observing the spectral line source when it should have been observing calibrators so the spectral line signature is present in the autocorrelation of 'other' sources. Careful flagging should be applied before using the ATCA autocorrelations for any calibration.
