General Comments. ( Brief data summary and scan listing )
C-band e-EVN run ToO on 30 September 2010. The scheduled data rate was 1024 Mbps. Participating telescopes were Ef, Cm, Jb2, Hh, Mc, On, Tr, and Wb. Mc and Hh were limited to 896 Mbps. This was first science e-VLBI observation with Hartebeesthoek.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.85 . ERI* = 1.00 . (Jb2=1, Cm=1, Hh=0.75/1, Mc=1, Ef=1, On=0.75/1, Tr=1, Wb=1)

Hh and On IF1-2 flagged, apparently bad amps (Hh reported RFI).

Comments from Yang Jun
Ef: The first 2.5 hours had bad attenuator level. The Tcal readout numbers  were useless and the determined Tsys were totally wrong. Manually interpolated some Tsys lines from the latest right Tsys measurements.
Cm: Used its rad file and set SEFD ~260 Jy.
Jb: Noise sources did not work. All the readout numbers were just noise. TPI data were used to get Tsys variation. Set FT=0.2 to get Tsys ~120 K.
Hh: nominal Tsys used (antabfs late for this first pipeline).

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).

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).
Comments.
On: sensitivity significantly lower than expected in the lower numbered IFs.
Tr,Wb: also somewhat lower sensitivity than expected.
