COVER LETTER: This is the schedule for the 1.3cm NME and ftp fringe-test on 3 June 2023 involving 19 antennas: Jb2 Ef Mc Nt O6 T6 Ur Tr Mh Ys Hh Kt Ky Ku Cm Da De Kn Pi. (Kt out -> 18 antennas) The NME uses the RCP-only 2 Gbps mode used in EC092 The schedule consists of long integrations on the strong calibrators J1058+0133 and J1159+2914, for ftp-fringe tests; and the sources J1152+2930 and J1221+2813 will be observed for phase-referencing test purposes. Seven ftp-fringe tests are scheduled throughout the experiment: 14:10:00 (scan 1, 4 sec, J1058+0133) 14:40:00 (scan 3, 4 sec, J1058+0133) 15:10:00 (scan 5, 4 sec, J1159+2914) 15:40:00 (scan 7, 4 sec, J1159+2914) 16:10:00 (scan 9, 4 sec, J1159+2914) 16:35:00 (scan 15, 4 sec, J1159+2914) 16:58:00 (scan 21, 4 sec, J1159+2914) 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) J1152+2930 93.0 J1058+0133 92.7 J1159+2914 94.3 J1221+2813 99.0 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.
