L-band e-EVN run on 10 February 2009. Aggregate bitrate was 512 Mbps with 2-bit sampling. There were in 8*8MHz subbands in both RCP and LCP. The target source was phase-referenced to J0137+3122. Effelsberg could not participate because of a crack in the azimuth rail. After the first hour, the Lovell Telescope stopped for a similar reason. Besides Cambridge, an additional MERLIN station, Knockin was made available for this run. The 2nd AIPS IFs of Kn is less well calibrated. The data playback problems with Westerbork (Mk5B->Mk5A+) seen in the January 2009 e-EVN run were solved by an alternative track mapping. IF1 Tsys data in WB were corrupted by RFI but the data were ok -used Tsys from IF2 for IF1 as well.
The EVN reliability indicator (ERI) for this experiment was
ERI = 0.58 . ERI* = 0.80 .
