The NME uses a standard setup with 2048 Mbps. The schedule consists of long integrations on calibrators J1751+0939 and J2031+1219 for ftp-fringe tests. The following ftp-fringe tests are scheduled throughout the experiment (UT times): 11:15:00 (scan 2, 2 sec, J1751+0939) 11:45:00 (scan 4, 2 sec, J1751+0939) 12:15:00 (scan 6, 2 sec, J1751+0939) 12:45:00 (scan 8, 2 sec, J1751+0939) *** 4Gbps portion *** 13:15:00 (scan 10, 2 sec, J2031+1219) 13:45:00 (scan 12, 2 sec, J2031+1219) Good luck with the session!
