Abstract
A data extraction from w422e, which had only the two GRTs. The survey extraction is a four hour segment with the longer of the two tracking passes. As the source is in the far south the (u,v) coverage from the GRTs is very limited, though on zooming in, source structure is apparent. A single elliptical gaussian provides a reasonable fit to the data. The best fit major axis is 0.36mas. An error of +/-0.03 on this value seems reasonable, as larger values are clearly discrepant.

Comments on Difmap processing
No gscal as only 2 GRTS plus HALCA. The full data set has a couple of near-crossing points which were inspected and the calibration found to be good. HALCA weights were set to 20 to match those of the GRTs.
