Abstract
Ceduna low, wrong polarisation? Pretty image of a bending jet - better than the PLS/UNSO ones. Why is this an VS11?

Comments on Difmap processing
Ceduna is very low (1/6) for J0403-36 & J0402-31. scaled up.

Flux and uv data matches the PLS model - roughly. I think mine is better & matches the axis.
