General Comments. ( Brief data summary and scan listing )
EH032A, L-band VLBI experiment on 2015 October 17. Participating telescopes were Jodrell Bank, Westerbork, Effelsberg, Onsala, Medicina, Torun, Shanghai, Urumqi, T6, Svetloe, Zelenchk, Badary, Hart. Data from Irbene (which was sheduled) did not arrive for correlation. Urumqi and Sardinia had fatal issues preventing fringes being detected for any experiment in this VLBI session. 'Fortunately', the worst issues were with the not so key stations (Sh has weak fringes, but T6 is OK, etc). There was no TSYS information available for JB and their log files showed problems too, thus we had to make an antab table containting a flat gain curve and apply blank TSYS info. Furthermore the Jb data was not flagged since the log file (used in making flag tables) was of no good use. Anyway, based on the pipeline results, Jodrel Bank data was salvaged and should be fine to use!


The EVN reliability indicator (ERI) for this experiment was ERI = 0.8 . ERI* = 0.8 . (Ef=1, JB=1, WB=1, MC=1, O8=1, SH=1, T6=1, Sv=1, Bd=1, Zc=1, Hh=1, Ur=0, TR=1, IR=0)

Weak fringes seen for Sh, it may be usable

Comments.
Several of the Eastern stations drop out due to low elevation at later times. JB is as described above.
