EVN: 2048 Mbps, 8 IFs, 32 MHz filters, L+R, 2-bit sampling evn4cm-2Gbps-32MHz.set with ON6_DBBC/Od, YS_DBBC/Yd, & EFF_DBBC/Ed DBBC3 testing COVER LETTER: This is the schedule for the 3.6cm NME FTP-FT on February 28, 2023 involving the following antennas (11): Wb1, Ef, Mc, Nt, On60, T6, Ur, Tr, Ys, Hh, Ib. The NME uses a standard 2 Gbps setup (16BBC/32MHz/dual), exc. Wb1 (1 Gbps). The NME lasts for 3 hours (28/02,12-15UT) with long scans on calibrators: J0237+2848, J0319+4130 (3C84) and J0530+1331 with ftp grabs every other scan at the following times (in UT): 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) 14:58:00 (scan 14, 2 sec, J0530+1331) -- Gabor Orosz Mattermost: coms.evlbi.org Schedule for EFF_DBBC (Code Ed ) Page 2 Network Monitoring Experiment UP: D => Below limits; H => Below horizon mask; W => still slewing at end; blank => Up.
