Hi all,

We have just finished a 12 hour evlbi "science" observation of the
supernova remnant 1987A, using the three LBA antenna Parkes, Mopra
and the ATCA. Data were sent from each telescope at 512 Mbps over
three dedicated 1 Gps lightpaths to JIVE for realtime correlation
(RTT 350msec). UDP data transport was used based on the "Verkouter"
UDP implementation on the Mark5.

The lightpaths were provided by a collaboration between AARNet,
CENIC, CANARY and SURFNet. Physically the paths goes from the
observatories to Sydney, across the Pacific to LA, Seattle, Chicago,
Amsterdam the finally to JIVE.

At the Australian end, data were recorded using the LBADR vlbi system
(a derivation of the PCEVN) with a Mark5 emulator wrapper and
realtime conversion of the data to Mark5b format. The data was
received at JIVE on a Mark5a+. The lightpaths worked well and we
could easily sustain 512 Mbps transfer for more than 12 hours. The
run went very smoothy.

Many thanks to all those who helped this happen - Particularly Mark,
Paul and Arpad at JIVE who have given us a lot of help setting up for
this experiment.

This work is part of the EXPReS project.
