The NME uses the 2Gbps setup that will follow in user experiments The schedule consists of long integrations on calibrators J1751+0939 and J2031+1219 for ftp-fringe tests. The following ftp-fringe tests are scheduled throughout the experiment (UT times): 12:10:00 (scan 1, 2 sec, J1751+0939) 12:40:00 (scan 3, 2 sec, J1751+0939) 13:10:00 (scan 5, 2 sec, J1751+0939) 13:40:00 (scan 7, 2 sec, J2031+1219) 14:10:00 (scan 9, 2 sec, J2031+1219) 14:40:00 (scan 11, 2 sec, J2031+1219) 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) J1751+0939 66.2 J2031+1219 105.2 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.
