The NME uses a standard setup with 128 Mbps. The schedule consists of long integrations on calibrators J0741+3112 and J0927+3902 for ftp-fringe tests. The following ftp-fringe tests are scheduled throughout the experiment (UT times): 128Mbps mode 12:15:00 (scan 2, 2 sec, J0741+3112) 12:45:00 (scan 4, 2 sec, J0741+3112) 13:15:00 (scan 6, 2 sec, J0927+3902) 13:45:00 (scan 8, 2 sec, J0927+3902) 4Gbps mode 14:15:00 (scan 10, 2 sec, J0927+3902) 14:45:00 (scan 12, 2 sec, J0927+3902) Good luck with the session!
