COVER LETTER: Dear EVN friends, This is the schedule for the 1.3cm FTP-FT on March 10 2011, involving 22 stations: Eb Jb2 On20 Mc Nt Tr Sv Zc Bd Ur Sh Hh Ys Mh Sr Ky, Ku, Kt, as well as Md Td Yd (Mc Tr and Ys with DBBC) and Sh65. The test uses a standard setup with 1024 Mbps and consists of two ftp fringe tests, interspersed with a longer set of scans on 0234+285 (~1.5 Jy source at 22 GHz). The two ftp fringe-test scans, start at: (1) 12:07:30 UT (scan 2, 2 sec) (2) 12:56:00 UT (scan 8, 2 sec) See you on Skype group chat and Good luck with the session!
