General Comments. ( Brief data summary and scan listing )
L-band short e-EVN run on 30 September 2010. The scheduled data rate was 1024 Mbps. Participating telescopes were Ef, Cm, Jb2, Mc, On, Tr, and Wb. Mc was limited to 896 Mbps. The Ef subreflector was not in the good position - no fringes.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.68 . ERI* = 0.68 . (Jb2=1, Cm=1, Mc=1, Ef=0, On=1, Tr=0.875, Wb=1)

Iridium RFI affecting IFs 1-2.

Comments.

Plots of the uncalibrated amplitude and phase against frequency channel
Comments.
Mc: first and last IFs attenuated because of known strong RFI.
Tr: no fringes in IFs L7-8 (BBC#8).

Comments.

TSYS against time
Comments.
Ef: poor Tsys data - used nominal sensitivity.
Wb: note IF2 amplitudes noisy, also Tsys. Replaced by IF1 Tsys values but it did not help all the problems with the amplitudes - most likely due to RFI.

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.
