Jb1, Wb, Ef, Mc, O8, T6, Ur, Tr, Sv, Zc, Bd, Hh, Ir, Sr, Ar, Dw. The NME uses a standard setup with 512 Mbps. The schedule consists of: - long integrations on calibrators J1824+1044, J1850+2825 and J0530+1331 for ftp-fringe tests; Ftp-fringe tests are scheduled every half hour throughout the experiment (UT times): 13:23:00 (scan 2, 2 sec, J1824+1044) 13:53:00 (scan 4, 2 sec, J1824+1044) 14:23:00 (scan 6, 2 sec, J1850+2825) 14:45:00 (scan 8, 2 sec, J0530+1331) 15:15:00 (scan 10, 2 sec, J0530+1331) 15:45:00 (scan 12, 2 sec, J0530+1331) The first three tests will include Arecibo. Good luck with the session!
