COVER LETTER: This is the schedule for the 6cm NME and ftp fringe-test on 25 October 2017 involving antennas: Jb2, Wb, Ef, Mc, Nt, On85, T6, Ur, Tr, Ys, Sv, Zc, Bd, Hh, Ir, Nk, and MERLIN outstations. The NME uses a standard setup with 512 Mbps during the first 2 hr. The NME uses a standard setup with 2048 Mbps during the last hr (Jb 2Gb). The schedule consists of: - long integrations on calibrator J1848+3219 for ftp-fringe tests; Strong fringes were found in N16C3 on this source. The following ftp-fringe tests are scheduled throughout the experiment (512 Mbps): 12:15:00 (scan 2, 2 sec, J1848+3219) 12:45:00 (scan 6, 2 sec, J1848+3219) 13:15:00 (scan 10, 2 sec, J1848+3219) 13:45:00 (scan 14, 2 sec, J1848+3219) Change to 2048 Mbps setup. 14:10:00 (scan 17, 2 sec, J1848+3219) 14:30:00 (scan 19, 2 sec, J1848+3219) 14:50:00 (scan 21, 2 sec, J1848+3219) 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) J1848+3219 82.0 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. 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
