COVER LETTER: This is the schedule for the K-band NME and ftp fringe-test on 05 November 2018 involving antennas: Jb2, Ef, Mc, Nt, On60, T6, Ur, Tr, Ys, Hh, Sv, Zc, Bd, Sr, Mh, Kt, Ky, Ku The NME uses a standard setup with 1024 Mbps. The schedule consists of long integrations on calibrators 3C345, J2123+0535 and J2148+0657 for ftp-fringe tests; The following ftp-fringe tests are scheduled throughout the experiment (1024 Mbps): 12:15:00 (scan 2, 4 sec, 3C345) 12:45:00 (scan 4, 4 sec, 3C345) 13:15:00 (scan 6, 4 sec, J2123+0535) 13:45:00 (scan 8, 4 sec, J2123+0535) 14:15:00 (scan 10, 4 sec, J2148+0657) 14:45:00 (scan 12, 4 sec, J2148+0657) Good luck with the session!
