Abstract These survey products were generated from an already-reduced GOT dataset (V115d). 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 most AIPS tasks were used. FITLD, FRING parameters are listed. I had problems concatenating this file and kept the three files separate until after SPLIT in AIPS. As a concequence the AIPS plots for the survey are three pages long, one plot per separate file. Also, three *TASAV* files exist. 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.
