The NME uses a standard 512 Mbps setup. The schedule consists of long integrations on strong calibrators (J0126+2559, J1051+2119) for ftp-fringe tests. (J1026+2559 ~1.4Jy/beam, J1051+2119 ~1.3Jy/beam) Four ftp-fringe tests are scheduled throughout the experiment: 12:09:00 (scan 2, 2 sec, J0126+2559) 13:15:00 (scan 8, 2 sec, J0126+2559) 13:43:00 (scan 11, 2 sec, J1051+2119) 14:49:00 (scan 17, 2 sec, J1051+2119) All antennas will participate in at least two FTP fringe tests. Please make sure that the autoftp is set up correctly. Thanks! Good luck with the session and see you on Skype!
