The baselines are still awfully big. The u,v,w as recorded should be
in seconds. Thus a baseline in seconds is its length in meters
divided by the speed of light in m/sec. We compute the baseline in
wavelengths by multiplying by the frequency in Hz.
The real and imaginary parts are pretty small ~ 1.e-7.
I assume that it is okay that the baseline is all 1-2 for source 1
with times changing by only a little.
