Comments on Difmap processing
Used UVtaper at 0.5 on 100Mlambdas to clean out the extended flux, then eliminated the taper in later iterations of clean/self-cal. Gscale corrections: IF1 VSOP_SC 1.12, MOP 0.92, SESHAN25 0.88, HOBART 0.90, IF2 VSOP_SC 1.11, MOP 1.04, SESHAN25 0.85, HOBART 0.90. Final image: Had a 0.153Jy/beam core, with a jet extending in close to an E-W direction.
