'Weak fringes' in a single-polarization experiment are always a slight
worry! Did you search the 'cross-hand' product Parkes-Mopra?
I'm very confident we have the polarization the right way around here (LCP
first). When the ATCA comes online that should prove it.
(CATIE needs to be set to;
FUN XX+YY XX-YY XX+YY XX-YY
to put LCP first, which is the reverse of the default).
Cheers,
