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!
