The NME uses a standard setup with 512 Mbps. The schedule consists of: - long integrations on strong calibrators like 3C84 and J0418+3801 for ftp-fringe tests; Four ftp-fringe tests are scheduled throughout the experiment: 12:09:58 (scan 2, 2 sec, 3C84) 13:04:58 (scan 8, 2 sec, 3C84) 13:59:58 (scan 14, 2 sec, J0418+3801) 14:44:58 (scan 19, 2 sec, J0418+3801) Please make sure that the autoftp is set up correctly. Thanks! Good luck with the session!
