General Comments. ( Brief data summary and scan listing )
C-band e-VLBI experiment observed in the 17-18 Oct. 2011 run. Participating telescopes were Ef, Hh, Jb2, On, Mc, Sh, Tr, Ys, and Wb. Sh was limited to 256 Mbps, Mc and Ys to 896 Mbps. There were no fringes to Hart in the EF023A part of the run. The target was phase-referenced to J1422+3223.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.67 . ERI* = 0.67 . (Ef=1, Jb2=1, Hh=0, Mc=1, On=1, Sh=0.6, Ys=1, Tr=0.875, Wb=1)
