Difmap Data Reduction Notes
Phase selfcal applied? Yes
Global amplitude selfcal (gscal) applied? No
Amplitude selfcal on non-global timescales used? No
Modelfit made and saved? Yes
Image Made and saved? Yes
Comments on Difmap processing
No amplitude self-calibration was done: it was impossible to get a good modelfit to the short baselines, as there is a tremendous amount of missing flux (>10 Jy) in the survey extraction.
