The FTP-FT uses a standard 2 Gbps setup (16BBC/32MHz/dual), exc. Wb1 (1 Gbps w/ 8 BBCs). The FTP-FT lasts for 1 hour (04/03,18-19UT) with scans on calibrator: J0854+2006 (OJ287) -- https://obs.vlba.nrao.edu/cst/calibsource/6716 with ftp grabs every other scan at the following times (in UT): 18:05:00 (scan 2, 2 sec, J1613+3412) 18:20:00 (scan 4, 2 sec, J1613+3412) 18:40:00 (scan 6, 2 sec, J1613+3412) 18:59:00 (scan 8, 2 sec, J1613+3412) -- Gabor Orosz Mattermost: coms.evlbi.org Schedule for TORUN (Code Tr ) Page 2 FTP Fringe Test UP: D => Below limits; H => Below horizon mask; W => still slewing at end; blank => Up.
