Comments on Difmap processing
J0609-15 (single baseline) is ~ 55% of the PLS flux J1215-17 (three baselines) is ~ 66% of the PLS flux. gscal on PLS model is Hh 1.2, Mp 0.8, Sh 1

In the end not applied as it did not make the image better (worse in fact). Matches well the USNO & PLS image (although with 60% of the flux)
