General Comments. ( Brief data summary and scan listing )
M band (6 GHz) network monitoring experiment, observed on 6th June 2006. Data rate was 128 Mbps (16 X 2 MHz subbands, dual polarization, two-bit sampling). The target source was '1222+037'. 3C273B was also observed as a calibrator.
9 stations participated. Torun lost 30 minutes due to a power supply problem.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.98 . ERI* = 0.98 . (MC=1, ON=1, WB=1, HB=1, TR=0.82, EF=1, NT=1, JB=1, CM=1)

Plots of the autocorrelations
Comments.
These plots show the problem with Darnhall, high total power in 'IF7 and IF8' in the terminology of these plots. Please see the NME report at ftp://ftp.jive.nl/monitor/n06m2.ps

plots of the uncalibrated amplitude and phase against time
Comments.
Ef-On IF3 \& IF4 LL shows no phase coherence and zero flux. This is the problem with VC03 that is mentioned in the NME report.

Plots of the uncalibrated amplitude and phase against frequency channel
Comments.
Da shows high flux in IF7 and IF8 (RR \& LL). Wb shows low flux in IF1 and IF2 in RR polarisation only throughout the first pass. Jb has low flux in IF 3 and IF 4 (LL only). On has very low flux in IF 3 and IF 4 (LL only).

The uncalibrated amplitude and phase of the crosshand correlations against frequency channel
Comments.
Da VC03 problem visible throughout.

TSYS against time
Comments.
Onsala shows spikes in Tsys around 19:30 UT.

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.
Onsala shows spikes around 19:30 UT and Mc shows spike aroung 20:30 UT.

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

Fringe-fit delay solutions
Comments.

Fringe-fit rate solutions
Comments.

Telescope bandpasses
Comments.
Onsala IF 2 and IF 3 (VC03) are missing in L polarisation. These plots show the problem with Darnhall, high total power in 'IF7 and IF8' in the terminology of these plots. Please see the NME report at ftp://ftp.jive.nl/monitor/n06m2.ps

Calibrated amplitude and phase against time (a priori amplitude calibration and fringe-fit solutions applied).
Comments.
Darnhall very poorly calibrated in IF8 RR and LL.

Calibrated amplitude and phase against frequency channel
Comments.
Da shows high flux in IF7 and IF8 (RR \& LL). Wb shows low flux in IF1 and IF2 in RR polarisation only throughout the first pass. Jb has low flux in IF 3 and IF 4 (LL only). On has been flagged in IF3 and IF4 LL as a result of low flux.
