COVER LETTER: Dear EVN friends, This is the schedule for the 18cm NME and ftp fringe-test on 16 June 2015, involving 15 antennas: Eb Wb Jb1 On85 Mc Nt Tr Sh Sv Zc Bd Hh T6 Sr Ar (+Wd). The NME uses a standard setup with 512 Mbps and consists of long integrations on strong calibrators J0854+2006, J0011+0823, J0126+2559, 4C39.25, and 0234+285. Six ftp tests are scheduled: (1) 10:05:58 UT (scan 2, 2 sec, J0854+2006) (2) 10:20:58 UT (scan 9, 2 sec, J0011+0823) for Ar (3) 11:25:58 UT (scan 12, 2 sec, J0126+2559) for Ar (4) 11:40:58 UT (scan 25, 2 sec, 4C39.25) (5) 12:23:58 UT (scan 34, 2 sec, J0854+2006) (6) 12:54:58 UT (scan 34, 2 sec, 0234+285 ) for Ar Please make sure that the autoftp is set up correctly. Good luck with the session and see you on Skype!
