General Comments. ( Brief data summary and scan listing )
K-band NME observed on 5 Mar 2007 (session 1/2007). 128 Mbps, 2-bit sampling, dual polarization. There were 2*16 MHz channels in both RCP and LCP. The experiment started with 4C39.25, then continued with phase-referencing between J0140+4658 and 0133+476, finally phase-referencing between NRAO512 and 3C345. There was a short CEPA scan at the end.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.84 . ERI* = 0.93 . (SH=1, MC=0.8, ON=1, HH=1, MH=1, EF=0.92, NT=1, JB=0.67)

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.
