General Comments. ( Brief data summary and scan listing )
EP102, L-band multi phase center experiment. Participating telescopes were Badary, Effelsberg, Hartebeesthoek, Jodrell Bank (LT), Medicina, Onsala (25m), Robledo, Svetloe, Tianma65, Torun, Urumqi, Westerbork (single dish) and Zelenchukskaya.

Fringe-finder: OJ287. Another bright calibrator: J1002+1216 (~100 mJy). There were two pointings in this experiment. The first one was centred on FIELD1, and this had seven phase centers (FIELD1--7). FIELD8 was a separate pointing. Both pointings used the same reference source J1000+1324 (~50 mJy). This pipeline includes only FIELD1 target from the first pointing (the other phase centers have another set of FITS files in the archive). In principle the same calibration tables should be used for all these phase centers, except that those will require primary beam corrections as well.

For some telescopes with no or insufficient calibration data nominal gain values are used in the antab file (BdJbRoSvTrUrZc). Torun data were flagged in this pipeline (very low sensitivity), as well as some subbands heavily affected by RFI.

The EVN reliability indicator (ERI) for this experiment was ERI = . ERI* = .
