The NME uses a standard 512 Mbps setup. The schedule consists of long integrations on strong calibrators (J1642+3948 aka. 3C345 and J1800+3848) for ftp-fringe tests. At 3.6cm, 3C345 (J1642+3948) is ~3Jy/beam and J1800+3848 is ~0.8Jy/beam) Four ftp-fringe tests are scheduled throughout the experiment: 09:29:00 (scan 4, 2 sec, J1642+3948) 10:09:00 (scan 8, 2 sec, J1642+3948) 10:59:00 (scan 13, 2 sec, J1800+3848) 11:39:00 (scan 17, 2 sec, J1800+3848) All antennas will participate in all FTP fringe tests. Please make sure that the autoftp is set up correctly. Thanks! Good luck with the session and see you on Skype!
