COVER LETTER: Dear EVN friends, This is the schedule for the 18cm FTP-FT on October 24 2013, involving 14 stations: Eb Wb Jb1 On25 Mc Nt Tr Sv Zc Bd Ur Sh Hh Ir The test uses a standard setup with 512 Mbps and consists of two ftp fringe tests, interspersed with a longer set of scans on 2005+403 (~2.5 Jy source at 1.4 GHz). The two ftp fringe-test scans, start at: (1) 13:04:30 UT (scan 2, 2 sec) (2) 13:53:00 UT (scan 8, 2 sec) See you on Skype group chat and 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) 2005+403 99.9 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.
