Comments on Difmap processing
J0204+15: 1.15 Jy Hobart low by ~4 J0423-01: 3.2 Jy, 0.6 mas Hobart low by ~10 J0141-09: PLS flux LOWER! Model not dis-similar, given the resolution difference. Used 2 min selfcal. Secondary component only allowed as the PLS, and the clean and the model all agree on the marginal component.

EBF: 11-OCT-2005:

Fits well with one component, elongated in VLBApls structure direction

Core is 0.35 +/- 0.5
