General Comments. ( Brief data summary and scan listing )
L-band e-EVN run on 19-20 May 2009. The data rate was 512 Mbps. Participating telescopes were Ef, Cm(+Kn), Jb1, Mc, On, Tr and Wb. Cambridge and Knockin was limited to 128 Mbps (Merlin microwave link). The target was phase-referenced to J0945+3534. Because of the slewing limitations, the Lovell Telescope skipped every other phase-reference scans. RFI caused some problems for most stations, especially in IFs7/8. Wb IF1 had very variable sampler statistics, but the data look ok. The lightpath went down for Medicina during the night.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.82 . ERI* = 0.82 . (Ef=0.95, Cm=0.95 (+Kn=0.95), Jb1=0.95, Mc=0.65, On=0.95, Tr=0.95, Wb=0.95 )

Plots of the autocorrelations
Comments.
Cm and especiall Kn IF2 autocorrelations are not perfect.
Lots of RFI for Mc, but intermittent RFI is seen at other stations as well.
Jb1 strong RFI in IF8.

plots of the uncalibrated amplitude and phase against time
Comments.
Mc lost about 3 hours before the end.

Plots of the uncalibrated amplitude and phase against frequency channel
Comments.
Jb1 IF7-8 affected by RFI.
Tr L5-6 low amplitudes because of RFI?
