Brief data summary
and
scan listing
)
C-band NME observed on Jun 2007 (session 2/2007). 256 Mbps, 2-bit sampling, dual polarization. There were 4*8 MHz channels in both RCP and LCP. The experiment started with 3C84 for D-term calibration. Then it continued with phase-referencing between 4C39.25 and J0916+3854. There was a short OQ208 scan at the end (D-term calibration). DA193 was used as bandpass calibrator.
No fringes found to Effelsberg. Also, EF VC05 still not functioning.
The EVN reliability indicator (ERI) for this experiment was
ERI = 0.8 . ERI* = 0.8 .
(Ef=0, Wb=1.0, Jb=1.0, On=1.0, Mc=1.0, Nt=1.0, Tr=1.0, Ur=1.0, Sh=1.0, Cm=1.0)

smaller the better).

For each fringed source, plots of amp/phase calibrated and with a model-line overplotted. Phase-referencing worked very well: target phases well reproduced by the model.
