The NME uses a standard setup with 2048 Mbps. The schedule consists of long integrations on calibrators J0237+2848 and DA193 for ftp-fringe tests. The following ftp-fringe tests are scheduled throughout the experiment (UT times): 12:10:00 (scan 2, 2 sec, J0237+2848) 12:40:00 (scan 4, 2 sec, J0237+2848) 13:10:00 (scan 6, 2 sec, J0237+2848) 13:40:00 (scan 8, 2 sec, J0237+2848) 14:10:00 (scan 10, 2 sec, DA193) 14:40:00 (scan 12, 2 sec, DA193) Good luck with the session!
