Abstract This dataset came as four separate files which I was unable to concatenate with DOCONCAT. There are thus 4 versions of most AIPS plots. All four files were combined into the same subarray using DBCON before exporting. Doing a straight fringe-fit found fringes only out to 00:00. Found more fringes by fringing ground data, applying ground corrections and averaging in frequency and time (using SPLIT and UVAVG) then searching for HALCA fringes. Found HALCA fringes out to ~1:00-1:30. Note that I usually do time and frequency averaging with SPLAT but that did not work on this data (dying with a signal 11 error). Suggested parameters for all AIPS tasks were used. CALIB was not run so the final SN and CL tables have non-zero phases in them. Imaging and model-fitting both went very well and produced good results.
