| Abstract
These survey products were generated from an already-reduced GOT dataset (V030a). 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. In order to find weak HALCA fringes, the ground telescopes were fringed first. These solutions were applied and the resulting data was averaged in frequency and time using SPLAT. This helped increase the SNR for the weak HALCA fringes. Because of this, the GRTs in the final fringe plots have zero delays and rates, and there are two TASAV files: the final version and the tables as they were before SPLAT was applied. 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. This dataset came from Steven Tingay and Matt Lister. |
