Jb2, Wb, Ef, Mc, Nt, O8, T6, Ur, Tr, Ys, Sv, Zc, Bd, Hh, Ir. The NME uses a standard setup with 512 Mbps. The schedule consists of: - long integrations on calibrators J0237+2848 and J0530+1331 for ftp-fringe tests; Ftp-fringe tests are scheduled every half hour throughout the experiment (UT times): 13:23:00 (scan 2, 2 sec, J0237+2848) 13:53:00 (scan 4, 2 sec, J0237+2848) 14:23:00 (scan 6, 2 sec, J0237+2848) 14:53:00 (scan 8, 2 sec, J0530+1331) 15:23:00 (scan 10, 2 sec, J0530+1331) 15:53:00 (scan 12, 2 sec, J0530+1331) 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 66.3 J0530+1331 102.2 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.
