Difmap Data Reduction Notes
Phase selfcal applied? Yes
Global amplitude selfcal (gscal) applied? Yes
Amplitude selfcal on non-global timescales used? Yes
Modelfit made and saved? Yes
Image Made and saved? Yes
Comments on Difmap processing
The source is extended and a modelfit was applied for relatively large gaussian. Gscal imprpve much KA amplitude, and then improve much the images.
