COVER LETTER: Dear EVN friends, This is the schedule for the 18cm NME on October 27 2013, involving 14 stations: Eb Wb Jb1 On25 Mc Nt Tr Sv Zc Bd Ur Sh Hh Ir The NME uses a standard setup with 512 Mbps and consists of four ftp fringe tests, interspersed with a long phase referencing cycle involving 2201+315 (4C+31.63, ~2 Jy source at 1.4 GHz) and a close position reference calibrator (J2157+3127, ~0.44Jy in S band and ~1.27deg away). The four ftp fringe-test scans, all of them on 2201+315, start at: (1) 13:12:30 UT (scan 4, 2 sec) (2) 14:15:30 UT (scan 17, 2 sec) (3) 15:23:00 UT (scan 31, 2 sec) (4) 15:52:30 UT (scan 37, 2 sec) See you on Skype group chat and Good luck with the session!
