Abstract
These survey products were generated from an already-reduced GOT dataset (V030g). 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.

The frequency table for this dataset was corrupted, as can be seen by examining the LISTR.LIS file. Frequency IDs 1, 2, and 3 should be identical. The FQ table was edited with TABED after splitting to make this correction. Fringes were found to HALCA throughout this experiment except for an hour near apogee during the TZ tracking pass.
