Abstract
These survey products were generated from an already-reduced GOT dataset (V030x). 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. The AIPS files for this experiment (except for the exported FITS file) were lost in a disk failure. Therefore no AIPS plots could be made for this survey dataset. However, the data are good and well calibrated in agreement with the standard procedures set out for the survey.

This dataset came from Steven Tingay.

Imaging and model-fitting both went very well and produced good results.
