General Comments. ( Brief data summary and scan listing )
C-band NME observed on 1 Mar 2007 (session 3/2005). 256 Mbps, 2-bit sampling, dual polarization. There were 4*8 MHz channels in both RCP and LCP. The experiment started with 3C454.3, then continued with phase-referencing between 3C454.3 and J2254+1341, finally phase-referencing between 0234+285 and J0232+2628. There was a short 3C84 scan at the end.

EF suffered some clock jumps from 08:44 to 09:14. JB was parked at 09:02 UT due to high winds for rest of experiment.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.80 . ERI* = 0.97 . (Ef=0.86, Wb=1.0, Jb=0.16, On=1.0, Mc=1.0, Nt=1.0, Tr=1.0, Ur=1.0, Hh=1.0, Cm=1.0)

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.
