The NME uses a standard setup with 512 Mbps. The schedule consists of long integrations on calibrators J0121+1149, J0956+2515, and J0927+3902. The following ftp-fringe tests are scheduled throughout the experiment (UT times): 12:15:00 (scan 2, 2 sec, J0121+1149) + Arecibo 12:45:00 (scan 4, 2 sec, J0121+1149) + Arecibo 13:15:00 (scan 6, 2 sec, J0121+1149) + Arecibo 13:45:00 (scan 8, 2 sec, J0956+2515) 14:15:00 (scan 10, 2 sec, J0956+2515) 14:45:00 (scan 12, 2 sec, J0927+3902) 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) J0121+1149 55.7 J0927+3902 55.9 J0956+2515 64.3 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.
