General Comments. ( Brief data summary and scan listing )
EC054C, L-band e-VLBI experiment (within the EC052F run) on 13 January 2016. ... Participating telescopes were Effelsberg, Jodrell Bank (Mk2), Hart, Medicina, Onsala (25m), (Torun), Westerbork (single dish). Arecibo co-observed the last target at the end, but was not scheduled to take part in the VLBI phase-referencing.

The targets J1819-1458 and J1854+0306 were phase-referenced to the calibrators J1825-1718 and J1907+0127, respectively. Note the region is heavily scatter-broadened. Another bright calibrators were 1749+096, 1821+107 and 2029+121.
Torun could not participate because of a problem with the 18cm receiver. In the first part of the run On was missing because the telescope was parked (strong wind gusts). Effelsberg data rates occasionally dropped to ~<500 Mbit/s for a short time. There are no Hartebeesthoek fringes on the phase-reference sources because these are scatter-broadened. Some subbands were flagged in this pipeline because of strong RFI in Mc, Jb2 and Wb.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.49 . ERI* = 0.72 . (Ef=0.9, Jb2=0.75/1, Hh=1, Mc=0.63/1, On=0.6/1, Tr=0, Wb=0.88/1, Ar=1)
