The FTP-FT uses a standard 1 Gbps setup (8BBC/32MHz/dual). The FTP-FT lasts for 1 hour (23/10, 10:30-11:30 UT) with long scans on calibrator: J1613+3412 -- https://obs.vlba.nrao.edu/cst/calibsource/12148 with ftp grabs every other scan at the following times (in UT): 10:35:00 (scan 2, 2 sec, J1613+3412) 10:50:00 (scan 4, 2 sec, J1613+3412) 11:10:00 (scan 6, 2 sec, J1613+3412) 11:29:00 (scan 8, 2 sec, J1613+3412) A longer NME will follow this short initial fringe test in two days. -- Gabor Orosz Mattermost: coms.evlbi.org Schedule for HART (Code Hh ) Page 2 FTP Fringe Test UP: D => Below limits; H => Below horizon mask; W => still slewing at end; blank => Up.

SCHED provides warnings at individual scans for distances less than 10 degrees. The distance from the Sun to each source in this schedule is: Source Sun distance (deg) J1613+3412 56.9 Barry Clark estimates from predictions by Ketan Desai of IPM scattering sizes that the Sun will cause amplitude reductions on the longest VLBA baselines at a solar distance of 60deg F^(-0.6) where F is in GHz.
