used nominal_tsys.pl HO had a mix up with cables and so did not record any usable data. HO was not correlated with this experiment.

Comments on Difmap processing
0204+15: Point source implies Sh scaled by 1.13. PLS scaled down by ~ 1.6.

0321+12: Complicated jet structure in the PLS and USNO observations. This will be very difficult with poor uv coverage. The PLS matches well. Used the very extended components and imaged/modfitted the core.
