COVER LETTER: This is the schedule for the 90cm NME and ftp fringe-test on 3rd Mar 2017 involving antennas: Jb1, Wb, Ef, Ar The NME uses a standard setup with 256 Mbps. The schedule consists of: - long integrations on strong calibrators J1925+2106, J2115+2933, and J2212+2355 for ftp-fringe tests; Four ftp-fringe tests are scheduled throughout the experiment: 14:13:00 (scan 1, 2 sec, J1925+2106) 14:43:00 (scan 3, 2 sec, J2115+2933) 15:13:00 (scan 5, 2 sec, J2115+2933) 15:43:00 (scan 7, 2 sec, J2115+2933) 16:13:00 (scan 9, 2 sec, J2212+2355) 16:43:00 (scan 11, 2 sec, J2212+2355) 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) J1925+2106 58.8 J2115+2933 43.7 J2212+2355 32.5 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.
