General Comments. ( Brief data summary and scan listing )
EG058D, C-band e-VLBI run on 2012 March 20-21. Participating telescopes were Jodrell Bank (MkII), Westerbork, Effelsberg, Onsala, Torun, Yebes, Hartebeesthoek, Shanghai and Arecibo. Medicina could not take part because of maintanance work. From the 2x2 hours the second part (with Arecibo) failed due to various issues at the correlator durng night. Part of the array kept observing the target after the first two hours, which is included in the EG058D data to somewhat compensate for the losses.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.5 . ERI* = 0.5 . (Ef=1, Jb2=1, Ys=1, On=1, Tr=0.88, Wb=1, Hh=1, Sh=1, Ar=1)
