General Comments. ( Brief data summary and scan listing )
L-band e-VLBI run observed on 16 February 2011. The scheduled data rate was 1024 Mbps. Participating telescopes were Ef, Jb1, On, Mc, Sh, Tr, and Wb. Mc was limited to 896 Mbps, Sh was limited to 256 Mbps.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.76 . ERI* = 0.86 . (Ef=0.94, Jb1=0.69/0.94, On=0.94, Mc=0.94, Sh=0.94, Tr=0.78/0.9, Wb=.0.94)

Plots of the autocorrelations
Comments.
Lots of RFI.
Jb1: broad RFI in IFs 5-6, but weaker than last time in January
Mc: strong RFI in IF2; most subbands have some RFI
Tr: strong RFI in IF2 and IF7 (see notes below on low amp)

plots of the uncalibrated amplitude and phase against time
Comments.
Short correlation job crash at the beginning
Tr: did not recover for ~10 more minutes after job crash

Plots of the uncalibrated amplitude and phase against frequency channel
Comments.
Mc: IF1 RFI filtered; IF2 low amplitude
Tr: IF2 and IF7(-8) low amplitude

The uncalibrated amplitude and phase of the crosshand correlations against frequency channel
Comments.

TSYS against time
Comments.
In general RFI affected IFs have noisier Tsys.
Sh: nominal values

Telescope sensitivities from the a priori TSYS and Gain curves (the square of this number gives the antenna noise (SEFD) in Jy - the smaller the better).
Comments.

Fringe-fit phase solutions (including Parallactic Angle correction).
