The NME uses a standard 2 Gbps setup (16BBC/32MHz/dual), exc. Wb1 (1 Gbps). The NME lasts for 3 hours (13/06, 12-15UT) with long scans on calibrators: J0927+3902 (4C39.25) and J1159+2914 https://obs.vlba.nrao.edu/cst/calibsource/7138 https://obs.vlba.nrao.edu/cst/calibsource/9104 with ftp grabs every other scan at the following times (in UT): 12:10:00 (scan 2, 2 sec, J0927+3902) 12:40:00 (scan 4, 2 sec, J0927+3902) 13:10:00 (scan 6, 2 sec, J0927+3902) 13:40:00 (scan 8, 2 sec, J0927+3902) 14:10:00 (scan 10, 2 sec, J1159+2914) 14:40:00 (scan 12, 2 sec, J1159+2914) 14:58:00 (scan 14, 2 sec, J1159+2914) -- Gabor Orosz Mattermost: coms.evlbi.org Schedule for SHANGHAI (Code Sh ) Page 2 Network Monitoring Experiment UP: D => Below limits; H => Below horizon mask; W => still slewing at end; blank => Up.
