The NME uses a standard setup at 2048 Mbps for the first 1.5 h and then moves to 4096 Mbps. The schedule consists of long integrations on calibrators 3C345 and J2031+1219 for ftp-fringe tests. The source J2035+1056 is observed to determine phase stability in phase-referencing calibration. The following ftp-fringe tests are scheduled throughout the experiment (UT times): 12:10:00 (scan 2, 2 sec, 3C345) 2 Gbps 12:40:00 (scan 8, 2 sec, J2031+1219) 13:10:00 (scan 14, 2 sec, J2031+1219) 13:40:00 (scan 20, 2 sec, J2031+1219) --- Moves to 4 Gbps at 13:42 UT. 14:10:00 (scan 26, 2 sec, J2031+1219) 4 Gbps 14:40:00 (scan 32, 2 sec, J2031+1219) 14:58:00 (scan 36, 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) 3C345 62.3 J2031+1219 91.1 J2035+1056 91.5 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. For common VLBI bands, this is: 327 MHz 117. deg 610 MHz 81. deg 1.6 GHz 45. deg 2.3 GHz 36. deg 5.0 GHz 23. deg 8.4 GHz 17. deg 15.0 GHz 12. deg 22.0 GHz 9. deg 43.0 GHz 6. deg
