On Mh and Ys. The NME uses a standard setup with 1024 Mbps. The schedule consists of: - long integrations on strong calibrators: for ftp-fringe tests; Ftp-fringe tests are scheduled every half hour throughout the experiment: 09:26:00 - J1642-0621 09:56:00 - J1642+6856 10:26:00 - J1642+6856 10:56:00 - 3C345 11:26:00 - 3C345 11:56:00 - 3C345 12:26:00 - 3C345 12:56:00 - 3C345 13:26:00 - 3C345 13:56:00 - 3C345 Clear skies!
