| Abstract
No good halca post 18:40. VLBApls survey sources will mainly resolve. The extension of the gaussian or double point matches the VLBApl and 2cm major axis. |

| Comments on Difmap processing
Selfcal on 5 mins. Resolving point source is all that we can model on a 2 GRT array. The PLS/UNO points to a much more complex source (jet to SE), but is in reasonable agreement. If we use an elliptical Gaussian or two points the major axis matches the expansion. |
