COVER LETTER: This is the schedule for the 1.3cm NME and ftp fringe-test on 8th Mar 2017 involving 16 antennas: Jb2, Ef, Mc, Nt, O6, Ur, Tr, Ys, Sv, Zc, Bd, Hh, Mh, Kt, Ky, Ku The NME uses a standard setup with 1024 Mbps. The schedule consists of: - long integrations on strong calibrators 0234+285 (J0237+2848) and DA193 (J0555+3948) for ftp-fringe tests; Five ftp-fringe tests are scheduled throughout the experiment (UTC times): 12:28:00 (scan 2, 2 sec, 0234+285) 12:58:00 (scan 4, 2 sec, 0234+285) 13:28:00 (scan 6, 2 sec, 0234+285) 13:58:00 (scan 8, 2 sec, DA193) 14:28:00 (scan 10, 2 sec, DA193) 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) 0234+285 59.0 DA193 100.7 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.
