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? No
Comments on Difmap processing
Insufficient data for closure, but modelled nevertheless. Phase called on 5 minute timescale. Fluxes are in line with ATCA observations and the PLS on the shortbaseline. PLS model does not resolve like the VSOP data.
