The NME uses a standard setup with 512 Mbps. The schedule consists of long integrations on calibrators J0237+2848 and J2139+1423 for ftp-fringe tests. Ftp-fringe tests are scheduled every 20 min throughout the experiment (UTC times): 12:10:00 (scan 2, 2 sec, J0237+2848) 12:30:00 (scan 4, 2 sec, J0237+2848) 12:50:00 (scan 6, 2 sec, J0237+2848) 13:10:00 (scan 8, 2 sec, J0237+2848) 13:30:00 (scan 10, 2 sec, J0237+2848) 13:50:00 (scan 12, 2 sec, J2139+1423) -- Arecibo joins 14:10:00 (scan 14, 2 sec, J2139+1423) 14:30:00 (scan 16, 2 sec, J2139+1423) 14:50:00 (scan 18, 2 sec, J2139+1423) The first five tests will include Asian stations + Hart. The last four tests will include Arecibo. Good luck with the session!
