The NME uses a standard setup with 1024 Mbps. The schedule consists of: - long integrations on strong calibrator, J0927+3902, for ftp-fringe tests; Four ftp-fringe tests are scheduled throughout the experiment: 12:09:58 (scan 2, 2 sec, J0927+3902) 13:04:58 (scan 8, 2 sec, J1043+2408) 13:59:58 (scan 14, 2 sec, J1043+2408) 14:44:58 (scan 19, 2 sec, J1104+3812) Please make sure that the autoftp is set up correctly. Thanks! Good luck with the session!
