The second half of the NME will run with the 3.6cm dual pol setup involving antennas: Wb, Ef, Mc, Nt, On60, T6, Ur, Ys, Hh, Sv, Zc, Bd, Ir. The NME uses a standard setup with 512 Mbps. The schedule consists of long integrations on calibrators J1751+0939 and J2031+1219 for ftp-fringe tests. The following ftp-fringe tests are scheduled throughout the experiment (UT times): 12:10:00 (scan 2, 2 sec, J1751+0939) --- SX512geo mode (No Wb) 12:30:00 (scan 4, 2 sec, J1751+0939) 12:50:00 (scan 6, 2 sec, J1751+0939) 13:10:00 (scan 8, 2 sec, J1751+0939) 13:30:00 (scan 10, 2 sec, J2031+1219) --- X512 mode (Wb comes in) 13:50:00 (scan 12, 2 sec, J2031+1219) 14:10:00 (scan 14, 2 sec, J2031+1219) 14:30:00 (scan 16, 2 sec, J2031+1219) 14:50:00 (scan 18, 2 sec, J2031+1219) Good luck with the session!
