Abstract These survey products were generated from an already-reduced GOT dataset (V147b1). The fully reduced GOT data were used to produce the survey-required AIPS plots (adhering as closely as possible to the most recently released VSOP survey documentation and scripts). A subset of antennas and timeranges were extracted to produce the VSOP survey dataset and the imaging and model-fitting for the survey were done on this "extracted" dataset. 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.
