COVER LETTER: This is the schedule for the K-band NME and ftp fringe-test on 29 October 2017 involving antennas: Ef, Mc, On60, Ys. Hh The NME uses a standard setup with 512 Mbps. The schedule consists of: - long integrations on calibrators 3C345 and J1751+0939 for ftp-fringe tests; The latter being included for the sake of high elevations at Hart The following ftp-fringe tests are scheduled throughout the experiment (512 Mbps): 12:15:00 (scan 2, 2 sec, 3C345) 12:45:00 (scan 6, 2 sec, 3C345) 13:15:00 (scan 10, 2 sec, 3C345) 13:45:00 (scan 14, 2 sec, 3C345) 14:10:00 (scan 17, 2 sec, J1751+0939) 14:30:00 (scan 19, 2 sec, J1751+0939) 14:50:00 (scan 21, 2 sec, J1751+0939) 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 63.5 J1751+0939 58.5 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.
