General Comments. ( Brief data summary and scan listing )
L-band e-EVN run on 20 May 2009. The data rate was 512 Mbps. Participating telescopes were Ef, Cm(+Kn), Jb1, Mc, On, Tr, and Sh. Cambridge and Knockin was limited to 128 Mbps (Merlin microwave link). The target was phase-referenced to M81; due to slewing limitations, Jb1 skipped every other phase-reference scans. RFI caused some problems for most stations, especially in IFs7/8. The source was not visible from Westerbork. The lightpath went down for Medicina during the night.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.67 . ERI* = 0.67 . (Ef=0.95, Cm=0.95 (+Kn=0.95), Jb1=0.95, Mc=0, On=0.95, Tr=0.95, Sh=0.93 )

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.

Comments.
Lost Mc.

Comments.
Jb1 IF7-8 affected by RFI.
Sh R7 missing, bad 'track' seen in more than one SU, looks like Sh problem.
