The NME uses a standard setup with 256 Mbps (and 2Gbps mode at the end); both as will follow in user experiments. The schedule consists of long integrations on calibrators 3C345, J2031+1219, and J2139+1423 for ftp-fringe tests. The following ftp-fringe tests are scheduled throughout the experiment (UT times): 256 Mbps 12:18:00 (scan 2, 2 sec, 3C345) 12:38:00 (scan 4, 2 sec, 3C345) 12:58:00 (scan 6, 2 sec, 3C345) 13:18:00 (scan 8, 2 sec, J2031+1219) 13:38:00 (scan 10, 2 sec, J2031+1219) 13:58:00 (scan 12, 2 sec, J2031+1219) 2Gbps 14:18:00 (scan 14, 2 sec, J2139+1423) 14:38:00 (scan 16, 2 sec, J2139+1423) 14:58:00 (scan 18, 2 sec, J2139+1423) Good luck with the session!
