C-band e-EVN run on 19-20 November 2009. The scheduled data rate was 1024 Mbps. Participating telescopes were Ar, Ef, Cm(+Da), Jb1, Mc, On, Sh, Tr and Wb. The project was observed in two blocks, the first part was observed with Arecibo, the second with Shanghai. The Lovell Telescope was parked because of high winds. Cambridge and Darnhall (limited to 128 Mbps) were only available for limited time for the same reason. During the night Effelsberg data had to be re-routed and as a consequence they were limited to 512 Mbps afterwards. Shanghai was limited to 512 Mbps. Arecibo started at 512 Mbps, but this had to be lowered to 256 Mbps after the nominally approved 4-10 UT range for high data rates was passed. In the last about 40 minutes Arecibo connection was lost. Medicina and Yebes participated at 896 Mbps. This was achieved by dropping the highest subbands only from the initial 1024 Mbps data stream. The correlation job had to be aborted/restarted a number of times in the second part.
The EVN reliability indicator (ERI) for this experiment was
ERI = 0.54 . ERI* = 0.91 .
(Ar=0.75, Cm=0.5/1 (Da=0.25/1), Jb1=0/1, Mc=1, Ef=0.75, On=1, Sh=1, Tr=1, Ys=1, Wb=1)
