Hi Simon,

Great news. Well done...
And I think you are right and it is the first time the LBA and VERA
antennas have observed together.

It will be great to progress beyond simple tests. As far as the LBA is
concerned we will be happy to see proposals in the system that also
require the JVN. If I recall correctly, under the APT guidelines the
same proposal should go to both networks with all the scientific and
technical details. If they both approve it, then the respective
schedulers can coordinate for time.

I appreciate that there are technical issues to solve like formats,
but I still think the key is good proposals into the systems.

I look forward to working in this mode.

Cheers
Tasso
