Brief data summary
and
scan listing
)
M band (6 GHz) network monitoring experiment (NME), observed on 14 March 2008. The data rate was 256 Mbps (8 X 8 MHz subbands, dual polarization, two-bit sampling). observed sources 3C84, 3C454.3 and 0234+285. Also 'J2210+2013' was calibrated using the phase-reference source 'J2212+2355'.
9 stations participated. Torun did not observe because of problem with one of the azimuth drives. In Westerbork was used in single dish mode. Westerbork also reported problems with BBC#1, data lost for part of the experiment on those channels. Cambridge has fringes only on IF4.
The EVN reliability indicator (ERI) for this experiment was
ERI = 0.58 . ERI* = 0.58 .

For the 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.
