General Comments. ( Brief data summary and scan listing )
S/X band network monitoring experiment, observed on 17 Jun 2009. Data rate was 256 Mbps (8 X 8 MHz subbands, RCP polarization, 2 bit sampling at the EVN stations, 1bit sampling at Kunming). The source 4C 39.25, 1156+295, and OQ208 were observed. The data were correlated in two passes. One is for S band data. The other is for X band data. Here, it is the S-band pypeline result.

8 stations participated. It is the first time for the Kunming 40m radio telescope to participate the EVN experiment. The first fringes to the Kuming telescope were successsfully deteced at S band. Yebes did not participate the observations due to failure of the H-maser. Noto had an unlocked BBC.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.75 . ERI* = 0.75 . (Ef=1, Mc=1, On=1, Ur=1, Km=1, Nt=0.88, Wb=1, Sh=1, Ys=0)


Plots of the autocorrelations
Comments.
Mc: Strong RFI in IF 1 and 4.


plots of the uncalibrated amplitude and phase against time
Comments.
Wb: no fringes because TADUmax can only sum either S or X band signal for the moment. Here, only the X band signal was selected.


Plots of the uncalibrated amplitude and phase against frequency channel
Comments.


The uncalibrated amplitude and phase of the crosshand correlations against frequency channel (not available)
Comments.


TSYS against time
Comments.
Km: Less Tsys data since the "tpicd" monitoring data were not available and no gain curve in the antab file.


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).
Comments.
SOINT=0.5 minute. Ef: reference antenna. Nt: no solutions in IF 3R.
