General Comments. ( Brief data summary and scan listing )
L-band e-EVN run on 10-11 September 2009. The data rate was 512 Mbps. Participating telescopes were Ef, Jb1, Cm(+Jb2+Kn), Mc, On, Tr and Wb. Cambridge, Jodrell MarkII and Knockin was limited to 128 Mbps (Merlin limitation). The target was phase-referenced to J0305+0523. Because of the slewing limitations, the Lovell Telescope (Jb1) skipped every other reference scans. RFI caused some problems for most stations, especially Medicina and Onsala. Wb IF1 was noisy. The Lovell Telescope had low sampler statistics, sensitivity was somwhat reduced. In the antenna table Jb is the LT, Jv is the MarkII telescope. MERLIN telescopes had the data in IFs 3-4. Medicina data missing from ~22:30 UT until ~1:45 UT. According to the logs, the antenna was off-source.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.86 . ERI* = 0.86 . (Ef=1, Jb1=0.75, Cm=1 (Jb2=0.96, Kn=1), Mc=0.54, On=1, Tr=1, Wb=1 )

Comments.
The amplitude calibration of this experiment was generally very good. (Note in the first half hour the sources were at a very low elevation.)
Jb, Cm and Kn had IF-to IF variability in amplitude correction factors.
Jv LCP looks poor, especially 3L.

Telescope sensitivities (the total AMP gain applied during both a priori and self calibration; the square of this number gives the antenna noise (SEFD) in Jy).
