The NME uses a standard 4 Gbps setup (32BBC/32MHz/dual), exc. Ur (2 Gbps w/ 16 BBCs) and Wb1 (1 Gbps w/ 8 BBCs). The NME lasts for 3 hours (22/02,14-17UT) with scans on calibrators: J0319+4130 (3C84) -- https://obs.vlba.nrao.edu/cst/calibsource/2564 J0530+1331 -- https://obs.vlba.nrao.edu/cst/calibsource/4162 J0555+3948 -- https://obs.vlba.nrao.edu/cst/calibsource/4449 with ftp grabs every other scan at the following times (in UT): 14:10:00 (scan 2, 2 sec, J0319+4130) 14:40:00 (scan 4, 2 sec, J0319+4130) 15:10:00 (scan 6, 2 sec, J0530+1331) 15:40:00 (scan 8, 2 sec, J0530+1331) 16:10:00 (scan 10, 2 sec, J0530+1331) 16:40:00 (scan 12, 2 sec, J0555+3948) 16:59:00 (scan 14, 2 sec, J0555+3948) -- Gabor Orosz Mattermost: coms.evlbi.org Schedule for WSTRBORK (Code Wb ) Page 2 Network Monitoring Experiment UP: D => Below limits; H => Below horizon mask; W => still slewing at end; blank => Up.
