The NME uses a standard setup with 512 Mbps. The schedule consists of: - long integrations on strong calibrators like 3C286 and 1848+283 for ftp-fringe tests; Six ftp-fringe tests are scheduled throughout the experiment: 12:09:58 (scan 02, 2 sec, 1848+283) 12:28:58 (scan 05, 2 sec, 3C286 - no Sh and Bd) 13:28:58 (scan 11, 2 sec, 1848+283) 13:43:58 (scan 13, 2 sec, 3C286 - no Sh, Ur, Bd, and Hh) 14:30:58 (scan 18, 2 sec, 1848+283) 14:46:58 (scan 20, 2 sec, 3C286 - no Sh, Ur, Bd, and Hh) Please make sure that the autoftp is set up correctly. Thanks! Good luck with the session!
