The NME uses a standard setup with 2048 Mbps. The schedule consists of long integrations on calibrators J0530+1331 and J2031+1219 for ftp-fringe tests. The following ftp-fringe tests are scheduled throughout the experiment (UT times): 14:15:00 (scan 2, 2 sec, J0530+1331) 14:45:00 (scan 4, 2 sec, J0530+1331) 15:15:00 (scan 6, 2 sec, J0530+1331) 15:45:00 (scan 8, 2 sec, J0530+1331) 16:15:00 (scan 10, 2 sec,J0530+1331) 16:45:00 (scan 12, 2 sec,J0750+1231) Clear Skies!

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) J0530+1331 99.7 J0750+1231 133.7 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.
