EVN: 4 Gbps, 16 IFs, 32-MHz filters, L+R, 2-bit sampling MER: 512 Mbps (1 x 64-MHz), UR: 2 Gbps (8 x 32-MHz), Wb: 1 Gbps (4 x 32-MHz) with ON8_DBBC/Od and YS_DBBC/Yd DBBC3-testing stations in parallel COVER LETTER: This is the schedule for the 6cm NME and ftp fringe test on 23 February 2023 involving 12 EVN antennas + eMERLIN out-stations: Jb1, Wb, Ef, Mc, Nt, O8, T6, Ur, Tr, Ys, Hh, Ib, Cm, Da, Kn, Pi, De. (plus Od and Yd for DBBC3 testing) The NME uses a standard setup of 4 Gbps, with eMERLIN (0.5 Gbps), Ur (2 Gbps), Wb (1 Gbps). The NME lasts for 3 hours and consists of long scans on calibrators J0237+2848, J0319+4130, and J0530+1331. The following ftp-fringe tests are scheduled throughout the experiment (UTC times): 12:10:00 (scan 2, 2 sec, J0237+2848) 12:40:00 (scan 4, 2 sec, J0237+2848) 13:10:00 (scan 6, 2 sec, J0237+2848) 13:40:00 (scan 8, 2 sec, J0319+4130) 14:10:00 (scan 10, 2 sec, J0319+4130) 14:40:00 (scan 12, 2 sec, J0530+1331) Benito Marcote Mattermost: coms.evlbi.org Schedule for URUMQI (Code Ur ) Page 2 Network Monitoring Experiment UP: D => Below limits; H => Below horizon mask; W => still slewing at end; blank => Up.
