Abstract
No Halca data is available. Good signal to noise data of GRTs baselines indicate the visibility 2 Jy at 2 Mlambda and 1 Jy at 120 Mlambda which are consistent with PLS measurements. Imaging was tried to yield the elongation toward NE direction though not much resolution to that direction because of poor uv-coverage.

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
The amplitude is consistent with PLS results. Only phase self-cal was performed with selfflag false, 3,4 mode. The closure phase is fulfiled only the first 15 minutes.
