Comments on Difmap processing
Based on J0204+15 (and VLBApls model) Multiplied Kal by two, i.e. Tsys of 100. Nominal Tsys is 50, and the logged value is 70.

EBF: 01-OCT-2005: Made a fit more consistent with VLBApls, with big faint blob to the south-east. The small component is 0.10 +/- 0.10 in size.
