COVER LETTER: This is the schedule for the 1.3cm NME and ftp fringe-test on 7th June 2018 involving 16 antennas: Jb2, Ef, Mc, Nt, O6, Tr, Ys, Hh, Sv, Zc, Bd, Sr, Mh, Kt, Ky, Ku Plus the eMERLIN outstations. The NME uses a standard setup with 1024 Mbps. The schedule consists of: - long integrations on strong calibrators OJ287 and J0927+3902 for ftp-fringe tests; Five ftp-fringe tests are scheduled throughout the experiment (UTC times): 12:15:00 (scan 2, 2 sec, OJ287) 12:45:00 (scan 4, 2 sec, OJ287) 13:15:00 (scan 6, 2 sec, OJ287) 13:45:00 (scan 8, 2 sec, OJ287) 14:15:00 (scan 10, 2 sec, J0927+3902) 14:45:00 (scan 12, 2 sec, J0927+3902) May the fringe be with you!
