The NME uses a standard setup with 512 Mbps. The schedule consists of long integrations on calibrators J0237+2848 and J2139+1423 for ftp-fringe tests. Ftp-fringe tests are scheduled every 20 min throughout the experiment (UTC times): 12:10:00 (scan 2, 2 sec, J0237+2848) 12:30:00 (scan 4, 2 sec, J0237+2848) 12:50:00 (scan 6, 2 sec, J0237+2848) 13:10:00 (scan 8, 2 sec, J0237+2848) 13:30:00 (scan 10, 2 sec, J0237+2848) 13:50:00 (scan 12, 2 sec, J2139+1423) -- Arecibo joins 14:10:00 (scan 14, 2 sec, J2139+1423) 14:30:00 (scan 16, 2 sec, J2139+1423) 14:50:00 (scan 18, 2 sec, J2139+1423) The first five tests will include Asian stations + Hart. The last four tests will include Arecibo. Good luck with the session!

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) J0237+2848 56.9 J2139+1423 31.8 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.
