COVER LETTER: Dear EVN friends, This is the schedule for the 1.3cm FTP-FT on March 04 2014, involving 19 stations: Eb Wb Jb1 On25 Mc Nt Tr Sv Zc Bd Ir Ur Sh Hh Ys, as well as Md Td Yd (Mc Tr and Ys with DBBC) and Sh65. The session uses a standard setup with 512 Mbps and consists of three ftp fringe tests, interspersed with a longer set of phase referencing scans on 3C 84 (~25 Jy source at 5 GHz), and a weaker calibrator. The three ftp fringe-test scans, start at: (1) 14:07:30 UT (scan 2, 2 sec) (2) 14:57:20 UT (scan 20, 2 sec) (3) 16:52:50 UT (scan 62, 2 sec) See you on Skype group chat and Good luck with the session!
