The schedule consists of long integrations on strong calibrators (0234+285 & 3C84) for ftp-fringe tests. At 18cm, 0234+285 is ~1.3 Jy/beam and 3C84 is ~10.4Jy/beam) Four ftp-fringe tests are scheduled throughout the experiment: 12:09:00 (scan 2, 2 sec, 0234+285, all ants) 12:54:00 (scan 8, 2 sec, 3C84, Hh ~20deg) 13:39:00 (scan 14, 2 sec, 0234+285, Sh & T6 ~15deg) 14:24:00 (scan 20, 2 sec, 3C84, no Zc; Sh, T6, Hh ~20deg) All antennas will participate in at least two FTP fringe tests. Please make sure that the autoftp is set up correctly. Thanks! Good luck with the session and see you on Skype!
