General Comments. ( Brief data summary and scan listing )
EW016, L-band e-VLBI experiment on 2014 December 3. Participating telescopes were Effelsberg, Hartebeesthoek, Jodrell Bank (MkII), Onsala, Shanghai and Torun. Noto 18cm was not ready in time. Westerbork could not participate. Medicina is still not available because of an antenna problem. Onsala had very weak fringes during the night.

Amplitude calibration of this run is rather uncertain. Jodrell Bank and Shanghai apparently had low sensitivity; amplitudes were scaled-up in the antab file but due to the low number of participating telescopes, and especially because of no matching E-W long baselines these are just best guess values. Further complication was the strong RFI that caused very low amplitudes in some of the subbands for some telescopes. In this pipeline some of the On, Tr and Jb subbands were flagged for RFI (counted in ERIVAL but not in ERI*).

The EVN reliability indicator (ERI) for this experiment was ERI = 0.41 . ERI* = 0.54 . (Ef=1, Hh=1, Jb2=0.5/1.0, On=0.94/1.0, Nt=0, Sh=1, Tr=0.88/1.0, Wb=0)
